GOP Sen. Ted Cruz sent out this tweet after the impeachment proceedings got underway:

NEWSFLASH for Nancy Pelosi and Adam Schiff: @realDonaldTrump invoking Constitutional privilege is not obstruction of Congress. If it were, nearly every president would have committed impeachable conduct. pic.twitter.com/lWeV32MxWH — Ted Cruz (@tedcruz) January 21, 2020

Well, he didn’t count on eagle-eyed CNN political analyst — and former Clinton White House Press Secretary — Joe Lockhart:

Senators on the floor are sworn to silence and have no electronic devices. So how is this Senator tweeting? Did he sneak a phone in. Is he willing to go to prison? Or is the tweet from someone other than Cruz. @jack you should investigate — Joe Lockhart (@joelockhart) January 21, 2020

Maybe Cruz should be impeached. As long as Joe Lockhart is watching him, he won’t get away with such a grave offense.

Prettttty sure that the Senate was sitting as a court of impeachment when "Elizabeth Warren" tweeted this out at 2:06pm today.https://t.co/YOUQUUidvy https://t.co/80wDsUbBWX — Drew McCoy (@_Drew_McCoy_) January 21, 2020

You cover politics and aren't smart enough to realize aides have access to their bosses twitter accts? Embarrassing. — Noah (@reeb1011) January 21, 2020

wow…you think that's embarrassing and not what's going on the Senate floor. Maybe you're not smart enough. — Joe Lockhart (@joelockhart) January 21, 2020

Joe is apparently unfamiliar with the expression “Quit while you’re behind.”

Gawd…..did you really think this was clever? — Annie_Bannany (@Annie_Bannany) January 21, 2020

“Jack you should investigate…” What planet are you on? — Jay Collinwood (@Jaycollinwood) January 21, 2020

GP Dude's still bitter about his boss getting impeached for actually perjuring himself. https://t.co/s62Cnb820G — The Gormogons (@Gormogons) January 21, 2020

It gets even better. Because Ted Cruz responded:

Zodiac claims another victim!

Hey, Joe. Next time you think about tattling on Ted Cruz, maybe try this instead:
