Throughout the public hearings, President Donald Trump has been very vocal on Twitter. The president wrote on Twitter that he will "strongly consider" Nancy Pelosi's invitation to have the president testify in the probe. Trump has not confirmed whether he would physically testify or provide written answers to questions.

The full tweet said, "Our Crazy, Do Nothing (where’s USMCA, infrastructure, lower drug pricing & much more?) Speaker of the House, Nervous Nancy Pelosi, who is petrified by her Radical Left knowing she will soon be gone (they & Fake News Media are her BOSS), suggested on Sunday’s DEFACE THE NATION...." He continued the tweet and said, "....that I testify about the phony Impeachment Witch Hunt. She also said I could do it in writing. Even though I did nothing wrong, and don’t like giving credibility to this No Due Process Hoax, I like the idea & will, in order to get Congress focused again, strongly consider it!"

Several media outlets reported that the committee is wrapping up its public hearings. The next step will be writing a report on the impeachment inquiry. No end date has been announced. Politico reported that Nancy Pelosi has "no idea" if this inquiry will be finished by the end of the year.
