Here's a quick summary of the latest news:
WHAT YOU NEED TO KNOW
— The White House acknowledged Thursday that Trump's decision to hold up military aid to Ukraine was linked to his demand that Kyiv investigate the Democratic National Committee and the 2016 U.S. presidential campaign. The admission from acting chief of staff Mick Mulvaney brought swift rebuke from Democrats, who cast his words as an admission of wrongdoing.
— Gordon Sondland, the U.S. ambassador to the European Union, said Thursday that Trump directed him and other envoys to work with his personal lawyer, Rudy Giuliani, on Ukraine policy. Sondland said he disagreed with the directive.
— Two businessmen pleaded not guilty Thursday to conspiring with associates of Giuliani to make illegal campaign contributions.
An interview with Laura Cooper, deputy assistant secretary of defense for Russia, Ukraine and Eurasia, was scheduled for Friday but has been postponed until Oct. 24. It is unclear if she will show up after Trump's vow of non-cooperation.
