After former national security adviser John Bolton said this week he would be willing to testify in the impeachment trial if called, Trump on Friday expressed concern about the precedent it would set in an interview with Fox News.
"Well, I think you have to invoke executive privilege for the sake of the office", Trump said when asked if he planned to evoke executive privilege if Bolton were called to testify.
House Speaker Nancy Pelosi signaled that she will turn the House articles of impeachment to the Senate as early as next week - allowing the impeachment trial to begin - even though a dispute over whether or not Senators will call witnesses remains unresolved.
Democrats are seeking testimony from Bolton and current White House Chief-of-Staff Mick Mulvaney on Trump’s alleged efforts to enlist Ukraine’s help in investigating allegations of corrupt business practices by his 2020 presidential rival Joe Biden's son Hunter in exchange for $600 million in military aid to Kiev.
A two-thirds Senate majority – 67 votes – would be needed to convict Trump and remove him from office.
