Testimony from a senior White House official on Tuesday appeared to contradict Energy Secretary Rick Perry's ardent denials that he ever heard former Vice President Joe Biden or his son Hunter discussed in relation to U.S. requests that Ukraine investigate corruption.

In his opening statement, Lt. Col. Alexander Vindman, a National Security Council official overseeing Ukraine policy, told House impeachment investigators that he objected to EU Ambassador Gordon Sondland's comments in a July 10 White House briefing — attended by Perry — requesting that Ukrainian officials investigate the 2016 U.S. election, the Bidens and the Ukrainian energy company Burisma that had employed Hunter Biden.
