President Trump's polling obsession doesn't appear to have diminished since 2016.

Trump is "fixated" on former Vice President Joe Biden as a potential 2020 threat, and over the past few weeks has "peppered aides on more than one occasion" about his poll numbers, Politico reported on Friday. It was previously reported that Trump sees Biden as the "most formidable" 2020 opponent, although publicly, Trump has shown no signs of nervousness, saying in October that a fight between the two "would not last long," per The Hill.

Biden has topped early Democratic primary polls, but Politico reports that Trump's advisers have assured him he has nothing to worry about and that the former vice president is essentially the Jeb Bush of 2020. Bush also led in some early 2016 Republican primary polls, earning 21 percent support in a March 2015 ABC News/Washington Post poll, which was conducted before Trump entered the race.

Trump's advisers have also apparently made the argument that there's a good chance Biden won't make it through the Democratic primary, and even if he does, he'll be "pulled to the left" and wouldn't be tough to defeat in the general election. Biden is still mulling over a possible 2020 bid but has not yet announced his decision. Brendan Morrow

The Game of Thrones series finale drew a record number of viewers to HBO on Sunday night, and not all of them left satisfied. On Monday night, the late-night shows bade farewell to the cultishly beloved drama in their own unique ways, some more elaborate than others. There are few, if any, spoilers.

At Jimmy Kimmel Live, Kimmel showed a sneak peak of one of the secretive Game of Thrones spinoffs HBO is promising, this one starring Bob Saget and Dave Coulier in their Full House roles, with a twist.

The Late Show's Stephen Colbert imagined what other TV shows HBO might stick dragons in, and laid out the story arc of that errant plastic water bottle.

Colbert's Late Show started off with a little fan fiction about Jaime Lannister.

On Conan, a super fan dressed as a Game of Thrones character complained that the current season of Wahlburgers was terrible, and he made Conan O'Brien and Andy Richter act out a very GoT-y scene of his own fan fiction.

Trevor Noah noted at The Daily Show that some fans are taking the finale so hard, a website is "offering therapy sessions for people upset about the ending of Game of Thrones. And let me just say, people, if you need therapy because a TV show ended, your life is too good, okay? I'm just going to tell you straight, you don't need a therapist, you need some credit card debt and an STD."

"Watching Game of Thrones is kind of like running a marathon," James Corden mused at The Late Late Show. "Even if you chose not to take part, you're still forced to listen to people at work talk about it forever." He joked that sadly, millions or people are discovering their friendship was based only on a shared HBO password, and "now if you want to watch dozens of odd characters scheme for power, you'll need to start following the 2020 Democratic race."

The Golden State Warriors eked out a 119-117 overtime win over Portland on Monday, sweeping the Trail Blazers 4 games to 0 in the NBA Western Conference finals. Monday's win sends the Warriors to their fifth consecutive NBA Finals. They have a week to rest before facing either the Toronto Raptors or the Milwaukee Bucks, and they hope to have one or both injured stars, Kevin Durant or Andre Iguodala, back in the game by then. The Bucks lead the Eastern Conference series 2-1, and Game 4 is Tuesday.

Warriors guard Stephen Curry and Draymond Green became the first teammates in NBA history to each get triple-doubles in a playoff game — Curry had 37 points, 12 rebounds, 11 assists; Green, 18 points, 14 rebounds, 11 assists. The Blazers were playing in their first conference finals since 2000. Peter Weber

A federal judge in Washington, D.C., handed House Democrats their first legal victory Monday in their fight to obtain President Trump's financial records, in this case from Trump's accounting firm Mazars USA. "It is simply not fathomable," Judge Amit Mehta wrote, "that a Constitution that grants Congress the power to remove a president for reasons including criminal behavior would deny Congress the power to investigate him for unlawful conduct — past or present — even without formally opening an impeachment inquiry." Mehta gave Trump a week to appeal, and Trump said he will do so.

The next legal battle involves a subpoena from the House Financial Services Committee for Trump's business and personal financial records from Deutsche Bank and Capital One. U.S. District Judge Edgardo Ramos in Manhattan is hearing Trump's motion to block that subpoena on Wednesday, and House lawyers quickly reminded Ramos that Mehta had just rejected "a substantially similar challenge by President Trump."

Ramos will be hearing Trump's request for a preliminary injunction, a step Mehta skipped, but Trump's basic legal argument is broadly similar in both cases: Congress is inappropriately investigating Trump's personal finances, without any legitimate legislative reason. If Ramos allows the subpoena, Trump's lawyers wrote last week, "nonstop investigations into the personal lives of presidents" will become "the new normal."

Trump refuses to release his tax returns, and his relationship with Deutsche Bank in has been a point of particular intrigue, most recently when The New York Times reported Sunday that Deutsche Bank money-laundering experts flagged several suspicious transactions from Trump-controlled accounts in 2016 and 2017, but executives in the private-banking division sat on the reports rather than passing them to government regulators.

Céline Dion joined James Corden for a special, Las Vegas edition of "Carpool Karaoke," which involved much more than just singing.

Dion passed out pairs of her shoes to unsuspecting people on the sidewalk, discussed the pitfalls of fame, made some seriously great facial expressions, and with her rendition of "Baby Shark," proved that she can make any song dramatic.

Of course, no Céline Dion "Carpool Karaoke" can end without a taste of "My Heart Will Go On," and the pair hopped out of the car and into a boat waiting for them in front of the Fountains of Bellagio. As very confused tourists watched from the Las Vegas Strip, Dion and Corden channeled their inner Jack and Rose, even dropping a certain piece of jewelry into the water. Watch the video here.

When Becca Bundy learned that Bill Cox needed a kidney, she had a feeling she would be the perfect match.

"I couldn't get it out of my head," Bundy told KARE 11. "I just said, 'I'm the one and I know it.'" The Cook, Minnesota, mother of four first met Cox two years ago, when her infant daughter, Hadley, had a seizure. She called 911, and Cox, a volunteer firefighter, was the first person to arrive. Bundy said she could tell Cox, 66, really cared about her daughter, and she remembered that when she ran into him at a benefit last year.

Cox was the bartender, and wore a T-shirt saying he was in kidney failure and looking for a donor. Cox was born with only one kidney, and by the time Bundy ran into him, he was losing hope of finding a donor. Bundy got tested, and after it was determined she was a match, the pair underwent surgery in February. "I feel pretty blessed to be chosen to be on his journey with him," Bundy said.

Cox is doing great — he's no longer on dialysis, and enjoys going with his wife, Terry, to visit Bundy and her family. "It's a lifetime bond that will never go away," Bundy said. Catherine Garcia

"We have been waiting with bated breath and it's finally happened, the thing we've all been waiting for: A Republican finally read the Mueller report," Stephen Colbert said on Monday's Late Show. That's not great for President Trump. Over the weekend, Rep. Justin Amash (R-Mich.) "read the redacted Mueller report and became the first Republican to say Trump 'engaged in impeachable conduct,'" he explained.

"So with that, I would like to offer the Republican Party this apology," Colbert said: "Now I know I give the GOP a hard time and often imply that you're a spineless group of self-interested toadies who'd rather see the country destroyed than stand up to an out-of-control narcissistic toddler. I was wrong — about one of you."

"Some say Amash has now made the calls for Trump's impeachment 'bipartisan,'" Colbert said, skeptically. "Well, yeah, technically. Like, technically, in high school once we had a girl at our Dungeons & Dragons party, but doesn't mean it was coed." Zero Republicans have joined Amash, and Colbert singled out Sen. Mitt Romney (R-Utah) for shunning courage and then mocked Trump for publicizing Amash's impeachment comments; he even sang a song about Amash in Trump voice. "If Trump didn't tweet about it, Amash would be a Page 3 news story, like war with Iran," he said.

"Speaking of which, up until now, Trump has been the voice of reason on Iran," Colbert said, acting disoriented by his own words. Well, that ended on Sunday. Watch below. Peter Weber
