A week after President Trump accused his predecessor, former President Barack Obama, of tapping his phones at Trump Tower during the campaign, then asked Congress to investigate, Congress appears to be getting a bit impatient with the lack of evidence. The heads of the House Intelligence Committee, Rep. Devin Nunes (R-Calif.) and Rep. Adam Schiff (D-Calif.), sent the Justice Department a letter last week giving the Trump administration until Monday to turn over any evidence it has to support the explosive claim, congressional aides told The Associated Press and NBC News over the weekend. FBI Director James Comey, who reportedly asked unsuccessfully that the Justice Department refute Trump's claim, was sent a copy of the letter as well.

Nunes suggested last week that Trump was either just asking questions about wiretapping or being taken too "literally" by the media, saying Trump is a "neophyte in politics." On Sunday, Schiff said he doesn't expect to see any evidence but plans to ask Comey about Trump's claims at a March 20 hearing. "I don't think anyone has any question about this, George," he told ABC News' George Stephanopoulos. "The only question is why the president would make up such a thing." House Speaker Paul Ryan (R-Wis.), who receives high-level intelligence briefings, also said on CBS Sunday that he has not seen any evidence to support Trump's wiretapping claim.

On CNN's State of the Union, Jake Tapper reminded Sen. John McCain (R-Ariz.) that nobody in government has really backed up Trump's accusation. "President Trump has to provide the American people, not just the intelligence committee but the American people, with evidence that his predecessor, the former president of the United States, was guilty of breaking the law," McCain said. "The president has one of two choices: Either retract, or provide the information that the American people deserve," he added, noting that this shouldn't be hard for Trump to prove: "All he has to do is pick up the phone, call the director of the CIA, director of national intelligence, and say, 'Okay, what happened?'"

At least six of President Trump's top advisers — including Reince Priebus, his former chief of staff, and former chief strategist Stephen Bannon — on occasion used private email accounts to talk about White House matters, several current and former officials told The New York Times on Monday.

On Sunday, a lawyer for Trump's son-in-law and adviser Jared Kushner confirmed that Kushner and his wife, Ivanka Trump, created a domain in December called IJKFamily.com for their personal email, and "fewer than 100 emails from January through August were either sent to or returned by Mr. Kushner to colleagues in the White House" from his account. Officials told the Times that in addition to Priebus, Bannon, Kushner, and Ivanka Trump — who reportedly used private emails to conduct business when she was both an unpaid adviser and later a formal adviser — chief economic adviser Gary Cohn and senior adviser Stephen Miller sent or received "at least a few emails on personal accounts," officials told the Times. It isn't known if any of the emails contained confidential information, or how many emails were sent and received from the private accounts.

For oversight reasons, government officials are supposed to use their work emails to conduct business, and if they do use private email accounts, they must forward any work-related emails to their government accounts for preservation purposes. During the campaign, Trump spent much of his time blasting Hillary Clinton for using a private email account during her tenure as secretary of state, leading his supporters at rallies in cheers of "Lock her up!"

Pittsburgh Steelers starting left tackle Alejandro Villanueva said Monday he's "embarrassed" when he sees photos showing him standing alone during the anthem before Sunday's game at Soldier Field.

"This national anthem ordeal has sort of been out of control, and there's a lot of blame on myself," Villanueva said. "I made Coach [Mike] Tomlin look bad, and that is my fault and my fault only. I made my teammates look bad, and that is my fault." Following President Trump's Friday comments — in which he called players taking a knee during the anthem to protest police brutality against blacks "sons of bitches" and said they should be fired — Tomlin said the Steelers would not take to the field during the anthem as a way to remain unified. "We're not going to let divisive times or divisive individuals affect our agenda," he added.

Villanueva, a West Point grad and Army Ranger who deployed to Afghanistan three times, said he had gone out to look at the flag before the game, and when the anthem started, he didn't want to move, and put his hand over his heart. "Unfortunately, I threw [my teammates] under the bus, unintentionally," he said. "Every single time I see that picture of me standing by myself, I feel embarrassed. We as a team tried to figure it out. Obviously, we butchered it…I'm not gonna pretend I have some kind of righteous voice."

Villanueva said he has no problems with players kneeling during the anthem, and many of the same players who take a knee have thanked him for his service, adding, "I will support all my teammates, and all my teammates and all my coaches have always supported me." Likely due to people thinking Villanueva was somehow protesting his team's decision not to come out on the field, his No. 78 jersey has been the top seller on NFLShop.com and Fanatics.com since yesterday, USA Today reports.

Late-night host and unlikely voice of the health-care debate Jimmy Kimmel was quick to tweet his support of Republican Sen. Susan Collins of Maine Monday evening, following her announcement that she won't vote for the the Graham-Cassidy health-care bill, the GOP's latest attempt to repeal ObamaCare.

"Thank you @SenatorCollins for putting people ahead of party," he tweeted. "We are all in your debt." Kimmel publicly entered the health-care debate earlier this year, after his son Billy was born with a heart condition and had to undergo emergency surgery when he was just three days old. Kimmel said he doesn't want anyone in the United States to worry about having to pay for life-saving care, and along with his wife, Molly McNearney, has tweeted his thanks to Republicans who have come out against the recent health-care bills — last week, after Sen. John McCain (R-Ariz.) announced he wouldn't vote for Graham-Cassidy, McNearney tweeted a photo of Billy in a robe with boxing gloves and thanked McCain for "fighting for kids like me."

Republican Sen. Susan Collins of Maine announced Monday evening she is opposed to both versions of the health-care bill sponsored by Sen. Lindsey Graham (R-S.C.) and Sen. Bill Cassidy (R-La.) that aims to repeal ObamaCare.

In a statement, Collins said she has three major concerns about the proposal Graham and Cassidy authored last week and the newest version they came up with over the weekend: both make "sweeping changes and cuts in the Medicaid program," "open the door for states to weaken protections for people with pre-existing conditions," and "would lead to higher premiums and reduced coverage for tens of millions of Americans." Collins said there are "many flaws" with the Affordable Care Act that need to be fixed, and her "focus will remain on remedying these problems."

Her decision effectively kills the bill, as Sen. John McCain (R-Ariz.) said last week he did not support it, and Sen. Rand Paul (R-Ky.) said he's a "no," although he did make a list of demands that, if met, would change his mind. Catherine Garcia

The Senate Finance Committee was forced to briefly delay its hearing on the Republican health-care bill on Monday after police were called in to remove loud protesters, many of whom were representing the disability rights group ADAPT, The Hill reports. The demonstrators chanted "no cuts to Medicaid, save our liberty" and "kill the bill, don't kill me," and could still be heard in the hallways after they'd been removed from the room.

Growing frustrated with the noise, panel chairman Orrin Hatch (R-Utah) snapped: "If you want a hearing, you better shut up."

On Sunday, Sens. Lindsey Graham (R-S.C.) and Bill Cassidy (R-La.) released a new draft of their bill designed to win over a small handful of holdout GOP senators. Jeva Lange

On Monday, White House Press Secretary Sarah Huckabee Sanders reassured Americans that President Trump did not actually declare war on North Korea via tweet.

Sanders' statement ran contrary to claims made earlier in the day by North Korea's foreign minister, Ri Yong Ho. Ri claimed Pyongyang now has the right to shoot down U.S. bombers in international airspace after Trump said Saturday that North Korea "won't be around much longer" if it keeps intimidating America.

"We've not declared war on North Korea," Sanders said. "And frankly the suggestion of that is absurd."

She went on to add: "It is never appropriate for a country to shoot down another country's aircraft when it's over international waters. Our goal is still the same. We continue to seek the peaceful denuclearization of the Korean peninsula. That's our focus." Watch below. Jeva Lange

After famously dubbing President Trump a "bum" over the weekend, LeBron James doubled down on his comments at the Cleveland Cavaliers' media event on Monday. "The thing that kind of frustrated me and pissed me off a little bit is that [Trump] used the sports platform to try to divide us," James said in response to Trump's comments about NFL protests as well as his decision to disinvite the Golden State Warriors' Stephen Curry from the White House. "It is so amazing what sports can do for everyone, no matter what shape or size or race or ethnicity or religion or whatever … It just brings people together like none other."

James added: "We're not going to let — I'm not going to let ... one individual, no matter the power, no matter the impact that he should have or she should have, ever use sport as a platform to divide us."

James also stressed that everyone should try every day to make a difference for others. "We know this is the greatest country in the world," James said. "It's the land of the free. But we still have problems just like everybody else, and when we have those problems we have to figure out how to come together and be as great as we can be as a people. Because the people run this country. Not one individual. And damn sure not him." Jeva Lange
