An improvised explosive device was detonated on a London Underground train, injuring at least 29 people during rush hour Friday morning. A manhunt is underway and police are treating the incident as terrorism. President Trump tweeted saying "Another attack in London by a loser terrorist." Trump went on to tweet support of his travel ban saying it should be "far larger, tougher and more specific-but stupidly, that would not be politically correct!"

    North Korea fired a ballistic missile over the northern Japanese island of Hokkaido. This was its second launch to flyover Japan in less than a month. The White House held a briefing where top officials said there are military options available for dealing with the North Korea crisis.

    Trump's new target: ESPN

    In a tweet this morning, Trump asked ESPN to apologize for "untruth" after anchor Jemele Hill tweeted earlier this week that the President is a "white supremacist who has largely surrounded himself w/ other white supremacists." CNN obtained a memo from the sports network's president that said, "ESPN is about sports." It is "not a political organization." Hill has not responded to the President's tweet.
