The Note: Bernie Heading to ‘The View’ (And The Vatican)

— -- NOTABLES

--HAPPENING TODAY -- BERNIE SANDERS ON ‘THE VIEW.’ The Vermont senator pays a visit to ABC’s “The View” which airs at 11 a.m. ET this morning. Sanders was a guest on the show back in February, where he tried the Ben and Jerry’s ice cream flavor named after him, shot some hoops with the co-hosts, and talked politics. His presidential opponent Hillary Clinton was a guest on “The View” on Tuesday.

--SANDERS TO VISIT VATICAN NEXT WEEK: Sanders will visit the Vatican next week to attend a conference on social issues, his campaign announced today, according to ABC’s ALANA ABRAMSON. The invitation was extended by the Vatican, Sanders said today. Sanders said on "Morning Joe" that he was "very moved" by the invitation. “I’m a big, big fan of the pope," Sanders said. "Obviously there are areas where we disagree, on women's rights or gay rights, but he has played an unbelievable role, an unbelievable role of injecting a moral consequence into the economy. “People think Bernie Sanders is radical," he added. "Read what the pope is writing.”

--SANDERS CAMP SAYS IT WILL ‘100 PERCENT’ CONTEST CONVENTION IF CLINTON DOESN’T CLINCH DELEGATE MAJORITY.  It’s not just the GOP that may be headed to a contested convention. Bernie Sanders' campaign manager believes the Democrats may be going in the same direction. Sanders campaign manager Jeff Weaver says that if Hillary Clinton fails to reach a majority of pledged delegates ahead of the Democratic convention, Sanders will “100 percent, absolutely” challenge her for the nomination -- even if Clinton has more votes than Sanders. “The way the math is right now, it is very, very, very unlikely that either candidate will arrive at the convention with enough pledged delegates to win the nomination,” Weaver said in an interview on ABC News’ “Powerhouse Politics” podcast. Clinton would need to win 63 percent of the 1,741 remaining pledged delegates up for grabs to clinch the nomination counting only pledged delegates before the convention, while Sanders would need to win 78 percent, ABC’s JORDYN PHELPS notes. Clinton currently has 1,280 pledged delegates while Sanders 1,030. Each candidate would need 2,383 delegates to clinch. http://abcn.ws/1Mif9bC LISTEN to full podcast: http://apple.co/21V9721

--SANDERS SURPRISES NEW YORKERS WALKING DOWN BUSY MIDTOWN STREET. Not to be outdone by Hillary Clinton, who took the subway Thursday morning, Sanders decided to go on a stroll in Midtown Manhattan. Accompanied by a dozen Secret Service agents and a handful of staff, Sanders surprised and delighted New Yorkers as he hoofed it Thursday evening. On his way to tape an interview, the Vermont Senator and Brooklyn native stopped for a snack at the Brooklyn Diner. ABC’s MARYALICE PARKS reports, he ate a bowl of chicken soup and an English muffin, while sitting at a booth near the window with his wife Jane. http://abcn.ws/1MXdQ1K
