Testimony from James Comey lit up Twitter on Thursday as people tuned in to see what the former FBI director testified about events surrounding his firing by President Donald Trump last month. Trump was uncharacteristically silent on the social media site.

A former federal prosecutor who, like Comey, was fired by Trump, weighed in on previous warnings from the president that he may have recorded his conversations with Comey:

Preet Bharara: "We can all agree with Jim Comey that, Lordy, we hope there are tapes."

Trump's sons leaped to his defense:

Donald Trump Jr.: "Hoping and telling are two very different things, you would think that a guy like Comey would know that. #givemeabreak"

Eric Trump: "Correct. Now let's stop this charade and get back to Jobs, HealthCare, Taxes, Infrastructure, our Military and Making America Great Again!"

Rep. Frank Pallone, a New Jersey Democrat, poked fun at the size of the crowd at the hearing:

"Tough turn of events for #Trump that there were more people in line for the #ComeyHearing than were at his inauguration."

The Republican National Committee questioned Comey's level of certainty:

"James "I could be wrong" Comey. #ComeyHearing #BigLeagueTruth"

Captain America actor Chris Evans begged Trump to chime in:

"I've never wanted Trump to tweet so badly in my entire life. Pick your phone up! Do it!! DO IT!!!!"

Kamala Harris, a Democratic senator from California, weighed in on the president's word choice:

"In my experience as prosecutor, when a robber holds a gun to your head and "hopes" for your wallet, "hope" is not the operative word."
