OFF TO THE RACES: Clinton wins Puerto Rico

Hillary Clinton won Sunday's Puerto Rico primary, putting her on the verge of clinching the Democratic nomination.

Remember David French? Well, he won't pursue an independent bid after all.

It's busy up on the Hill for Paul Ryan. From POLITICO: "Speaker Paul Ryan has dealt with one big problem — what to do about Donald Trump — but he returns to Washington this week facing a critical legislative stretch leading to the national conventions in mid-July, with problems looming everywhere. Ryan and the House GOP leadership face serious challenges to pass a fix for Puerto Rico's debt debacle, funding to fight the Zika virus and the annual spending bills they deemed a top priority. A decision also has to be made on whether to press ahead with the impeachment of IRS Commissioner John Koskinen."

Nebraska Sen. Ben Sasse says he's open to backing Gary Johnson.

NBC's Pete Williams offers a rundown of the big cases pending in the final month of the Supreme Court's term.

The New York Times reports on the new firm Firehouse Strategies established by former Rubio aides Terry Sullivan, Alex Conant, and Will Holley.

CLINTON: Bill Clinton responded to pro-Sanders hecklers, saying "If I were them, I’d be screaming too because they know they will be toast by election day."

Her latest ad hits Trump for his comments about Judge Gonzalo Curiel.

Her 2008 press secretary, Jay Carson, writes in the New York Times: "So to all the Sanders staff members and supporters who are as hurt and dismayed as I was, who feel that their candidate is right and the opponent dead wrong, who want to keep fighting to the convention and beyond: I get it. I’ve been there (with Howard Dean and Bill Bradley as well). But please learn what I have learned and don’t let your anger get the best of you. The consequences of doing anything that will help Donald Trump win are catastrophic."

Pressure is mounting for her to hold a press conference after reporters rebuffed her campaign’s claims of accessibility.

SANDERS: The New York Times reports on how supporters are still flocking to Bernie Sanders' rallies despite the long odds. "Some are there in solidarity with his message, and others because they believe Mr. Sanders when he says, against the odds, that he can still snag the nomination at the party’s convention in July. And then there are many who, regardless of their outlook on the race, are streaming in for what they believe may be their last glimpse of a political phenomenon."

How did Sanders lose his chance? The Washington Post does a deep dive. "As it became clear that Sanders was gaining credibility, though, he struggled to connect with black and Latino voters, as well as with older Democrats, groups that carried Clinton’s candidacy. Sanders repeatedly clashed with another vital constituency — the party leaders whose votes as superdelegates he would ultimately need to pry the nomination away from Clinton. Sanders also overestimated the power of his economic message and, adamant that he run the kind of positive campaign that had been his trademark in Vermont, initially underestimated the imperative to draw sharp contrasts with Clinton."

The Wall Street Journal, on what's next for Sanders: "A split is emerging inside the Bernie Sanders campaign over whether the senator should stand down after Tuesday’s election contests and unite behind Democratic front-runner Hillary Clinton, or take the fight all the way to the July party convention and try to pry the nomination from her."

TRUMP: The New York Times reports that he's bringing on Jim Murphy as his new political director.

He suggested that a Muslim judge might also be biased against him.

Republicans have pushed back against his comments about a Hispanic federal judge, including Mitch McConnell on Meet the Press.

Over the weekend, former attorney general Alberto Gonzales said Trump has the right to ask if Curiel is fair.

He shared a tweet purporting to show a black family that's supporting Trump. The problem? They're not.

"A growing number of Republican lawmakers and strategists fear that Donald Trump’s hostile remarks about minorities and his un­or­tho­dox strategy have imperiled his campaign at the end of a five-week head start on Democratic front-runner Hillary Clinton that they hoped would fortify him heading into the general election," writes the Washington Post.

From the New York Times: "Mr. Trump is not running a campaign in the modern sense — or what was the modern sense until about yesterday. Rather, he oversees a prolific content production studio that has accomplished what every major media conglomerate is trying to pull off with mixed success. It has managed to produce a huge amount of inexpensive programming that has consistently dominated the ratings and the conversation across the entire new-media landscape — cable news, broadcast news, radio, Twitter, Facebook and who knows what else."
