North Korea's leader Kim Jong Un (left) gestures next

North Korea pledges denuclearization, but skepticism abounds

North Korea's pledge to shutter its nuclear test facility next month and allow unprecedented access to the site drew praise — and skepticism — from experts who cite Kim Jong Un's history of bait and switch on denuclearization of the Korean Peninsula. "History cries out for us to be skeptical," said Harry Kazianis, defense studies director at the Center for the National Interest. Republicans and Democrats on intelligence committees warned, too, that President Trump needs to be cautious about talks with the dictator. "We need to be very skeptical,'' said Sen. Roy Blunt, R-Mo. Plans are underway for Trump to meet with Kim, but the timing and location for the meeting aren't finalized.

Comedian Michelle Wolf tears into Sarah Huckabee Sanders at correspondents' dinner

Sarah Huckabee Sanders attended Saturday night's White House Correspondents' Dinner to represent the Trump administration. She ended up with a front-row seat to her own roasting, courtesy of comedian Michelle Wolf. The evening typically includes playful roasts of the president. Wolf, however, held nothing back. "She burns facts and then she uses that ash to create a perfect smoky eye," Wolf said of Sanders, the White House spokeswoman. "Maybe she's born with it, maybe it's lies. It's probably lies." Not everyone in the audience appreciated Wolf's humor. Former White House press secretary Sean Spicer wrote that the dinner was a "disgrace." President Trump skipped the dinner for the second year in a row, instead holding a rally in Washington, Mich.

Trump: Democrat should resign after VA pick's reputation 'shattered'

President Trump called for a high-ranking Democratic lawmaker to resign Saturday after reports that at least one of the accusations that ended his bid to lead Veterans Affairs could be untrue. Navy Rear Adm. Ronny Jackson came under harsh criticism after colleagues accused him of improperly dishing out opioids, drinking on the job and crashing a government car while drunk. The accusations were compiled by a Senate committee, and Montana Sen. Jon Tester, the highest-ranking Democrat on it, said the accusations still needed investigating when they were released last week. "Allegations made by Senator Jon Tester against Admiral/Doctor Ron Jackson are proving false," Trump tweeted Saturday, adding that "his reputation has been shattered."

One-handed draft pick makes NFL history

Shaquem Griffin's NFL draft dream came true on Saturday. The Central Florida linebacker was selected by the Seattle Seahawks in the fifth round , becoming the first one-handed player to be drafted in the modern era. He will play alongside his twin brother, Shaquill Griffin, who was a third-round pick of the team last year and started 11 games at cornerback. Griffin had his left hand amputated when he was 4 because of his amniotic band syndrome, a prenatal condition that caused the hand to be underdeveloped. More from Saturday at the NFL Draft:

•	Pick-by-pick analysis from Rounds 4-7
•	Cowboys land Tavon Austin from Rams, trade Ryan Switzer to Raiders
•	9 NFL veterans who have been put on notice after NFL draft

France's first lady says Melania Trump endures strict security, can't go outside

France's first lady Brigitte Macron said in an interview that Melania Trump is "actually really fun" but that strict security limits her freedom. "She can't even open a window at the White House," Macron said in an interview published Saturday in Le Monde . "She can't go outside. She's much more constrained than I am. I go out every day in Paris." She also said that Trump "works very hard to hide (her) strong personality" and that people over-interpret Melania's sad appearances in public. During the three-day trip, she and Melania visited the National Gallery of Art while Emmanuel Macron and President Trump held closed-door negotiations.
