Trump cancels his planned summit with Kim Jong Un... (TheBlaze)

The White House released a statement on Thursday announcing the cancellation of President Donald Trump's planned June 12 summit with Kim Jong Un. The open letter from the president to Kim cited a “statement” made by North Korea as the reason for the cancellation, although it is not entirely clear at this point what that statement was. Even before this announcement, the summit had been increasingly in doubt. North Korea threatened to cancel the summit earlier this month, after the U.S. conducted military exercises with South Korea. The South Korean president called an emergency meeting after the White House's announcement, which occurred at around 10:45 P.M. in South Korea.

...just hours after the news broke that North Korea had destroyed tunnels at its Punggye-ri nuclear site (BBC)

Foreign journalists in North Korea reported that they witnessed the destruction of the tunnels. However, international investigators were not allowed to see the extent to which the site had been dismantled. North Korea announced in April that it would be shutting down this site in April as a sign of cooperation, but at the time Chinese scientists speculated that the site was actually being shut down because the North Koreans had inadvertently collapsed part of a mountain.

Trump tells Congressional Republicans that he won't accept any immigration deal that doesn't include a wall (Reuters)

President Donald Trump told Congress via Fox News that he would not accept any immigration deals that did not also include the border wall. “Unless it includes a wall, and I mean a wall, a real wall, and unless it includes very strong border security, there’ll be no approvals from me,” he announced. Trump had expressed disappointment when March's omnibus spending bill only included funding for 33 miles of border fence, and not the funding for the wall that he had hoped it would.

Trump says NFL players who kneel “maybe shouldn't be in the country” (TheBlaze)

Commenting on the recent ruling by the NFL that players who refused to stand for the national anthem could wait in the locker room until it was over, President Trump suggested that these players might want to leave the country. “Well, I think that’s good,” Trump said. “I don’t think people should be staying in locker rooms. But still, I think it’s good. You have to stand proudly for the national anthem, or you shouldn’t be playing, you shouldn’t be there. Maybe you shouldn’t be in the country.”

The ACLU sued Ohio, claiming that gerrymandering was unfairly helping Republicans (TheBlaze)

The American Civil Liberties Union accused Ohio Republicans of changing congressional districts in the state to benefit themselves. “Such gerrymandering not only violates democratic principles but is unconstitutional,” according to the lawsuit, which also called it “one of the most egregious gerrymanders in recent history.” Gerrymandering allows  the party in power to reshape districts to ensure that its candidates get elected. Gerrymandering in Maryland got so out of hand earlier this year, with Democrats trying to redraw districts to ensure that Republican candidates had no way of winning, that the case is now being heard before the Supreme Court.
