If any members of the GOP wanted to argue that U.S. policy toward Ukraine was being conducted without President Donald Trump's blessing or knowledge, they will be sorely disappointed with new testimony from acting U.S. Ambassador to Ukraine William Taylor.

On Wednesday, Taylor wrote in his prepared opening remarks that a member of his staff was privy to a conversation between Trump and U.S. Ambassador to the European Union Gordon Sondland in July during which it became clear that the president was aware of the pressure campaign to secure investigations into his political rivals.

At one point, Sondland told Taylor's staff member that Trump was more concerned with those investigations than he was with Ukraine.
