This day will go down in history as one of the more momentous days in the disastrous Trump presidency:
Masha Yovanovitch testified about being fired for her Ukraine anti-corruption work, so that Rudy and the three amigos could do their dirty work. During her testimony Trump attacked her on Twitter.
David Holmes testified about hearing Trump ask about the Biden investigations a day after the July 25 call with the Ukraine president.
Trump appealed to the Supreme Court to be able to hide his taxes from Congress.
