WASHINGTON (Reuters) - President Donald Trump's withholding of $391 million in military aid to Ukraine was linked to his request that the Ukrainians look into a claim - debunked as a conspiracy theory - about the 2016 U.S. election, a senior presidential aide said on Thursday, the first time the White House acknowledged such a connection.
Trump and administration officials had denied for weeks that they had demanded a "quid pro quo" - a Latin phrase meaning a favour for a favour - for delivering the U.S. aid, a key part of a controversy that has triggered an impeachment inquiry in the House of Representatives against the Republican president.
