One of President Trump's closest allies in the Senate is not buying his theory about the disappearance of journalist Jamal Khashoggi.

Sen. Lindsey Graham (R-S.C.) on Tuesday said that he believes the missing Washington Post columnist was murdered and that it was likely "orchestrated at the highest levels of government," per CBS News' Alan He.

Trump suggested on Monday that "rogue killers" may have been responsible for Khashoggi's disappearance, but Graham doesn't "think it was a rogue event." Graham said Saudi Crown Prince Mohammed bin Salman is "the one pulling the strings right now." But Trump on Tuesday, seemingly without skepticism, promoted the crown prince's claim that he has no knowledge of Khashoggi's fate.

Khashoggi arrived at the Saudi consulate in Istanbul, Turkey, earlier this month and has not been heard from since. Turkish officials told the United States they found evidence he was murdered and dismembered by a Saudi security team, and gave The Washington Post scans of seven men they believe were part of the Saudi team responsible. Trump promised that "answers will be forthcoming shortly" as Saudi Arabia will "rapidly expand" its investigation. But Turkish officials told the Post that there has been a "lack of Saudi cooperation" in the investigation and that it appears the consulate was cleaned and repainted before they could examine it.

Graham said the Saudi crown prince is "very schizophrenic," and told Fox & Friends that he has "got to go." Until something new happens in Saudi Arabia, Graham added, he has "no interest in engaging with this government" because he "cannot imagine a more blatant example of contempt for a relationship than this."

Mary Oliver, the beloved and prolific poet whose work reflected her reverence of nature, died Thursday at her home in Florida. She was 83, and the cause of death was lymphoma, according to her literary executor, Bill Reichblum. Oliver made her literary debut in 1963, at age 28, and won the Pulitzer Prize in 1983 for her collection American Primitive, then the National Book Award for poetry in 1992 for New and Selected Poems.

Born and raised in the Cleveland suburb of Maple Heights, Oliver escaped what she called an abusive and "dysfunctional" home life by exploring the nearby woods and writing poetry. She met her partner, Molly Malone Cook, at the New York home of the late poet Edna St. Vincent Millay, whose papers she helped organize after high school. Cook died in 2005.

Oliver's poems mostly centered on animal life and the natural world. "One of her favorite adjectives was 'perfect,' and rarely did she apply it to people," The Associated Press notes. In her 2004 essay collection Long Life, Oliver wrote that outwardly "there's never been a day that my friends haven't been able to say, and at a distance, 'There's Oliver, still standing around in the weeds. There she is, still scribbling in her notebook.' But, at the center: I am shaking; I am flashing like tinsel."

Oliver's poem "When Death Comes," from New and Selected Poems, ends with some thoughts about her own death:

When it's over, I want to say all my life

I was a bride married to amazement.

I was the bridegroom, taking the world into my arms.

When it's over, I don't want to wonder

if I have made of my life something particular, and real.

I don't want to find myself sighing and frightened,

or full of argument.

I don't want to end up simply having visited this world.

Oliver's final anthology of poems, Devotions, was published in 2017. Peter Weber

President Trump "appears to be on a collusion course with the law right now, and his alleged lawyer Rudy Giuliani was back on CNN last night and Rudier than ever," Jimmy Kimmel said on Thursday's Kimmel Live. If we didn't have video of his "crazy appearance on Chris Cuomo's show," it would "almost be too much to believe." Giuliani claimed incorrectly that he'd never said there was no collusion between Trump's campaign and Russia, so either there's "another Rudy Giuliani out there," Kimmel said, or Giuliani's lying — again. "Poor Rudy. Someday he's going to be in a mental facility telling the nurses that he used to be the mayor of New York and they'll be like, 'Uh-huh.'"

Kimmel also had some fun with the story about Trump ordering fixer Michael Cohen to hire a guy to rig some online polls, Cohen paying him a fraction of the cash in a Walmart bag, then hiring him to create a @WomenforCohen account. "I may have underestimated Michael Cohen," he said. "He might be a lot more hilarious that I ever imagined."

"It's crazy that Michael Cohen was rigging polls for Trump while Trump was out there complaining that the polls were rigged," Trevor Noah said at The Daily Show. "But one place where there's definitely no collusion is between Rudy Giuliani's brain and his mouth." He showed the clip: "Did Giuliani just admit that there was collusion? I think he did, and look at their faces. Like, neither of them can believe what just happened." Maybe Giuliani's antics are intentional, Noah mused. "Maybe the master plan is to keep creating so many new scandals that Robert Mueller can never finish his investigation."

"It really does seem like the pressure of the job is getting to Rudy," giving the latest of his "trademark accidental confessions," Seth Meyers said on Late Night. He ran through Giuliani's ever-shifting collusion story. "If this keeps going, Rudy is going to be telling Trump, 'It's not jail, it's a gated community.'" Watch below. Peter Weber

During a 2005 trip to southern Africa with his mother, 10-year-old Winston Duncan was inspired to start a nonprofit that, 14 years later, is still going strong.

Duncan met kids with holes in their shoes who walked miles to school and saw old women who shuffled down the streets, and wanted to make it easier for them to get around. Along with his mother, Dixie Duncan, he launched Wheels for Africa. People from his hometown of Arlington, Virginia, and the surrounding area donate bicycles to the organization, and after they are fixed up, the bikes are sent to people in need. Over the last 14 years, more than 8,000 bikes have been donated, with most going to African countries.

Last weekend, Duncan, his mom, and a small group of volunteers went to Puerto Rico for the first time, where 400 bikes were given to people still reeling from the devastation caused by Hurricane Maria in 2017. On Friday, the team spruced up the bikes, and on Saturday, the bicycles — along with helmets — were distributed to recipients. Now 24, Duncan is a graduate of Bard College and working at a political consulting firm. He told The Washington Post he hopes that Wheels for Africa's young volunteers see how privileged they are, and "think about giving back." Catherine Garcia

After buying some lottery scratchers earlier this month, Tyler Heep found himself with a winning ticket. Sure, it was only for $1, but the Des Moines, Iowa, man still thought that was something worth celebrating.

It turns out, the Iowa Lottery agreed. Heep went to lottery headquarters to cash in his winning ticket, and asked for one of the large novelty checks that are given to people who win big. "They decided to treat me like a million dollar winner," Heep told WHO-TV. "The guy came down the stairs and they took me into the back room where the camera was with the Iowa Lottery logo. Sure enough they wrote me the $1 check and had me hold it up and took the picture."

Heep used his lottery win to pay for half a gallon of gas. Catherine Garcia

The 27-day-old government shutdown "is getting ugly, and it was never a beauty queen," Stephen Colbert said on Thursday's Late Show. On Wednesday, House Speaker Nancy Pelosi (D-Calif.) asked President Trump to postpone or scrap his State of the Union address until after the government reopened, citing security concerns, and on Thursday, 45 minutes before Pelosi was supposed to get on a plane to visit NATO allies in Belgium and U.S. troops in Afghanistan, Trump informed her that he was canceling her trip.

"Now, Trump has the power to do this because Pelosi was flying military transport and he's the commander-in-chief, but Trump did give her another option": Fly commercial, Colbert said. "I'm sure JetBlue offers daily nonstop flights to a war zone." And not only did Trump spoil Pelosi's top-secret trip, he referred to her as "Madame" Speaker, not Madam Speaker, he noted. "A 'Madame speaker' is what Trump uses to order at a drive-thru brothel."

Trump is clearly urging Pelosi to fly commercial "like it's the worst thing he could think of," Trevor Noah said at The Daily Show. "That's hard-core, though, right? Canceling her flight right before she's about to take off. That's like the complete opposite of a romantic comedy." To be fair to Trump, he said, "Nancy Pelosi's letter was a little bit snarky, right? But it's crazy that Trump's GPS never takes him onto the high road."

Noah dipped into Cardi B's viral plea to end the shutdown — "How cool would it be if Cardi B somehow ended the shutdown? Like, we find out that Trump is a major fan because 'Bodak Yellow' is his favorite song, and also the color of his hair" — and he brought Michael Kosta out to discuss the GoFundMe campaigns of furloughed federal workers and other ways people are coping with the shutdown.

Rep. Jason Smith (R-Mo.) apologized to Rep. Tony Cárdenas (D-Calif.) on Thursday after he yelled "Go back to Puerto Rico!" as Cárdenas waited to speak on the House floor.

Smith had his outburst after Congress had adjourned and lawmakers were arguing over a bill to fund the government through the end of next month. Cárdenas said at first, it wasn't clear who shouted, and House Majority Leader Steny Hoyer (D-Md.) scolded his colleagues, saying, "I would hope that we could refrain from any implications that have any undertones of prejudice or racism or any kind of -ism that would diminish the character and integrity of one of our fellow members." Cárdenas told The Washington Post that hours later, Smith called him and "took responsibility for the comment and sincerely apologized." Cárdenas, the son of Mexican immigrants, accepted.

Joey Brown, Smith's communications director, told the Post that Smith was "speaking to all the Democrats who were down vacationing in Puerto Rico last weekend during the shutdown, not any individual." About 30 House and Senate Democrats visited Puerto Rico to bring attention to the fact that the island is still trying to recover from Hurricane Maria. Cárdenas is the chairman of the Congressional Hispanic Caucus' fundraising arm, Bold PAC, and organized the delegation. Catherine Garcia
