William B. Taylor Jr., acting ambassador to Ukraine, testified Wednesday in the first open hearing of the impeachment inquiry about a July phone call between President Trump and U.S. ambassador to the European Union Gordon Sondland that was overheard by a member of Taylor’s staff in which Trump purportedly asked about “the investigations.”

The conversation was said to have occurred on July 26, a day after Trump pressed Ukrainian President Volodymyr Zelensky to investigate former vice president Joe Biden and his son Hunter Biden at a time when U.S. military aid to Ukraine was being withheld.

Trump, asked about Taylor’s new testimony, said he had no recollection of such a call with Sondland.

Besides Taylor, members of the House Intelligence Committee also heard from George Kent, deputy assistant secretary of state for European and Eurasian affairs.
