President Donald Trump on Monday, Oct. 14, questioned if House Intelligence Committee Chairman Adam Schiff (D-Calif.) told a whistleblower to get his phone call with Ukrainian leader so wrong, insisting the whistleblower must be identified and testify.

President Trump made his request one day after Schiff changed his mind when saying a testimony from the whistleblower, who helped spark the House Democrats’ impeachment probe against the president, might not be necessary.
