Newly released interview transcripts from the Senate Judiciary Committee show Donald Trump Jr. struggling, in real time, to keep his story straight.

The panel interviewed Trump Jr. about the 2016 meeting between Trump campaign officials and a Kremlin-linked Russian lawyer who came to offer "dirt" on then-candidate Hillary Clinton. Lawmakers wanted to know whether Trump Jr. knew of any interactions between Trump campaign personnel and Russian government officials. "I was aware of none," said Trump Jr., in a seemingly definitive statement within his I-don't-remember-filled interview.

So Trump Jr. didn't even know about the meetings between Russian Ambassador Sergey Kislyak, then-National Security Adviser Michael Flynn, and senior adviser Jared Kushner? "If I could scratch my last statement," Trump Jr. said, "yes, I did read about that after the fact."

Okay, let the record show that Trump Jr. knew about the meetings, but not until they were reported in the press. But lawmakers pressed further: Did Trump Jr. know about the meetings when they occurred? "I knew of something," said Trump Jr. "I believe there was a meeting there. I wasn't part of the meeting, but yes, I believe I was aware that it had occurred."

Trump Jr.'s redo constituted a complete 180 on his original answer, though he didn't offer any additional detail on what he knew about the meetings. The president's son additionally said that he had walked in on a December 2016 meeting between Flynn, Kushner, and Kislyak that took place in his office, but said he didn't know what it was about and didn't stay to find out.

Tuesday's Late Show came at the end of a tumultuous couple of days for President Trump. Having just returned from a "disastrous" trip around Europe, during which he managed to bash NATO and rub shoulders with Russian President Vladimir Putin, Trump had some mopping up to do upon his return home.

In a press conference on Tuesday, Trump went into "emergency spin mode," Colbert said, listing his version of various events — including a weird fib about his meeting with Queen Elizabeth II — in an effort to make it into what Colbert calls the "Lying Hall of Fame."

But perhaps the biggest walk-back came after Trump stood next to Putin and told a room full of reporters that, despite conclusions to the contrary from American intelligence agencies, he was confident Russia did not meddle in the 2016 presidential election. "I don't see any reason why it would be [Russia]," Trump said. "That needs no clarification," Colbert assured, and then showed a clip of Trump saying his statement needed some clarification. "Okay, I stand corrected," Colbert said. "Alright Mr. President, I'll bite. Let's see how dumb you think the American people are."

Trump insists he simply misspoke. What he meant to say was, "I don't see any reason why it wouldn't be Russia."

"Yes, the sentence should have been that," Colbert said. "It was not that, but then again who among us hasn't said the exact opposite of what he just said in front of cameras on multiple occasions?" He finishes with a sick burn on Trump's "double negative" flub. Watch below. Jessica Hullinger

Researchers say that with temperatures rising in Canada's high Arctic, hundreds of glaciers are shrinking and many could soon vanish.

They used satellite imagery to study 1,773 glaciers on Ellesmere Island, the most northerly island in the Arctic Archipelago, and found that from 1999 to 2015, 1,353 shrank significantly, and a few disappeared completely. "What we found is a loss of three complete ice shelves," Adrienne White, a glaciologist at the University of Ottawa, told The Guardian. "In terms of glaciers that terminate on land, we've lost three small ice caps." From 1948 to 2016, the annual average temperature in northern Ellesmere Island increased by 6.48 degrees Fahrenheit, one of the fastest rates of anywhere on Earth.

White said none of the glaciers are showing any signs of growing, and when they "break away, all of a sudden there's nothing holding back these ecosystems that have been growing and developing for thousands of years. And they're gone before we even have the chance to study them." Catherine Garcia

During an interview with Fox News' Tucker Carlson that aired Tuesday night, President Trump said he's been thinking about the different ways Russia assisted the United States in the past.

During World War II, "Russia lost 50 million people and helped us win the war," he said. "I was just saying to myself the other day, you know, Russia really helped us. I'm not pro-Russia, pro-anybody, I just want to have this country be safe." He doesn't "want nuclear weapons, even people thinking about it," he added. "Russia and the United States control 90 percent of the nuclear weapons in the world, and getting along with Russia, and not only for that reason, is a good thing, not a bad thing."

Carlson asked Trump if Russia is "our chief adversary," and Trump said they have a "strong military" but their economy is "much smaller than China. I don't even want to use the term 'adversary.' We can all work together, we can do great, everybody can do well, and we can live in peace." Watch more of the interview in the video below. Catherine Garcia

President Trump came out on Tuesday with what he called a "clarification" of remarks he made in Helsinki on Monday, but CNN's Chris Cuomo and his giant computer screen weren't buying it.

While standing next to Russian President Vladimir Putin, Trump had an "epic fail in front of the world," Cuomo said, choosing Putin's "lies over his own country's truth." Trump on Tuesday said he misspoke, and meant to say "I don't know why it wouldn't be" Russia that meddled in the election, rather than "would." Cuomo had the portion of his remarks up on the screen, and ripped apart this explanation, going sentence by sentence.

Trump believes when the 2016 election is attacked, it "delegitimizes his win," Cuomo said, and "if it comes down to what is best for Trump or what is best for you, you're going to lose, and the world saw this yesterday and it was shameful." The most authentic proof of this is found in Trump's prepared remarks from Tuesday. They were typed, but Trump wrote in huge letters on top, "There was no colusion [sic]."

"Why?" Cuomo said. "Even though it has nothing to do with saying it is true that Russia attacked us, it is what he cares about, and you know it's authentic because he misspelled collusion and that is something he does, he misspells words." Trump also crossed out a line about bringing those involved "in that meddling to justice," and that's because "he hates the notion that there could be any sense of justice, fairness under law, that involves punishing him or anyone around him," Cuomo said. "The insistence on covering for himself cost our country a lot of legitimacy in Helsinki." Watch the video below. Catherine Garcia

Rep. Martha Roby was victorious Tuesday night, winning the Republican primary runoff in Alabama's 2nd congressional district.

She defeated Bobby Bright, a former Democratic congressman who became a Republican and vocal supporter of President Trump. After the Access Hollywood tape came out in October 2016 that showed Trump bragging about assaulting women, Roby said she would not vote for him, and that was used against her by Bright and the other Republican candidates during the campaign. In the June primary, Roby was unable to get more than 50 percent of the vote, and had to face Bright in the runoff election.

Since the election, Roby has praised Trump and visited the White House multiple times, and last month, he tweeted his endorsement of her. With nearly half of all precincts reporting, Roby had 67 percent of the vote, compared to Bright with 33 percent. Catherine Garcia

During a forum on gun control last week in Tucson, a Republican candidate for Arizona's Legislative District 2 stood up and said that he is proof of the importance of, in case of an attack, having a "good guy there with a gun."

Bobby Wilson said that when he was a teenager, he shot and killed a person who came into his room and wanted him dead, The Arizona Republic reports. "You can pass all the laws you want to in this world, and when you've got somebody out there that wants to harm somebody, they're going to do it if you don't stop them," he said.

The person he killed wasn't a burglar or a stranger, but rather his mother, Lavonne. Wilson was 18 and living in Hugo, Oklahoma, when the incident occurred. He said he woke up one morning "to find a rifle in my face," and he ended up having to dodge six bullets. He reached for the gun he kept under his bed, and used that to shoot his mom. The story doesn't end there, though. His younger sister, Judy, was also killed; Wilson said his mother swung her gun and accidentally hit her in the back of the head, killing the 17-year-old.

Wilson told The Arizona Republic there were glass containers in his room filled with gasoline, and when the bullets started to fly, several shattered. When he went to turn on the light, a spark landed on the ground and the house went up in flames. He said it wasn't until he became a lawyer years later did he remember all this, because he had amnesia after the shooting.

Newspaper reports from the time say Wilson confessed to shooting his mother, and when his sister ran at him, he crushed her skull with the rifle. He placed their bodies on a bed, then set the house on fire. He was tried on homicide charges, but after a jury agreed he had amnesia, the judge halted the trial until he could remember what happened. After seven years, Wilson asked for the charges to be dismissed, and a judge agreed. Read more about this bizarre tale at The Arizona Republic. Catherine Garcia

Walter Carr wasn't going to miss his first day of work, even if it meant getting up at midnight and walking 20 miles.

Carr, 20, lives in Homewood, Alabama, and he needed to get to Pelham, where he would start his job with the Bellhops moving company. His car had broken down, and he decided he would walk, so after just four hours of sleep, he set out on his journey. About 10 miles in, Carr had to take a break because his legs hurt, and a police officer pulled over to check on him. After hearing Carr's story, the officer and two others took him to breakfast, and he was dropped off at the home of Jenny Lamey.

When Lamey found out what Carr went through to get to her house, she asked him if he would like to rest, but he declined, and said he wanted to get to work. Carr told Lamey's children that when he was five, his home was destroyed during Hurricane Katrina, and also that after he earns his associate's degree later this year, he's going to start boot camp with the Marines. Lamey decided to start a GoFundMe to raise money for Carr to fix his vehicle, and she also shared his story with Bellhops CEO Luke Marklin, who was so impressed he drove from his home in Chattanooga to visit his "incredible" employee for lunch.

Carr didn't just get to share a meal with his boss, though. The Lamey family, the police officers he met, and his new Bellhops colleagues were waiting for him at a hotel, where Marklin surprised Carr with the keys to the Ford Escape SUV he drove to Alabama. "Walter truly raised the bar," he told ABC News. Carr was shocked, and said he was grateful and happy to have inspired so many people. Catherine Garcia
