Trump lashes out at Puerto Rico

The war of words between President Donald Trump and the mayor of San Juan, Puerto Rico, continues. When Vice President Pence visited the hurricane-ravaged island last week, he promised the administration would be with Puerto Rico every step of the way.

Trump tweeted on Thursday that "… We cannot keep FEMA, the Military & the first responders, who have been amazing (under the most difficult circumstances) in P.R. forever!"

Mayor Carmen Yulín Cruz fired back at the president: "@POTUS your comments about Puerto Rico are unbecoming of a Commander in Chief they seem more to come from a 'Hater in Chief'."

Chief of Staff John Kelly made a surprise appearance at Thursday's White House press briefing to take reporters' questions. He said the administration will stand with Puerto Ricans until the "job is done" but also said that the president's tweet about FEMA and the military is correct: "They will not be there forever," he said.

Kelly also denied that his relationship with the president is so strained that he is planning to quit.

The White House said the U.S. is pulling out of the United Nations cultural organization, known as UNESCO. The Trump administration said the organization is anti-Israel and needs fundamental reform. The withdrawal takes effect at the end of 2018.
