A top White House adviser with direct knowledge of President Donald Trump's push for Ukraine to investigate Democrats resigned late Thursday _ less than 24 hours before he was expected to testify in the impeachment inquiry, according to a senior administration official.
Tim Morrison, a senior member of the White House National Security Council, informed his bosses that he has "decided to pursue other opportunities," the official told the New York Daily News, speaking on condition of anonymity.
The official said Morrison has been considering his departure "for some time."
"We wish him well," the person added.
The announcement came one day before Morrison was expected to go before impeachment investigators and discuss Trump's attempts to pressure Ukrainian officials to investigate Joe Biden and other Democrats before the 2020 election while using nearly $400 million in U.S. military aid as leverage in an apparent quid pro quo.
