The White House makes the statement in response to David Holme's and Fiona Hill's testimonies.
From the White House:
“As has been the case throughout the Democrats’ impeachment sham, today’s witnesses rely heavily on their own presumptions, assumptions and opinions. These two witnesses, just like the rest, have no personal or direct knowledge regarding why U.S. aid was temporarily withheld. The Democrats’ are clearly being motivated by a sick hatred for President Trump and their rabid desire to overturn the 2016 election. The American people deserve better.” — Stephanie Grisham
