Tapper, who hosts CNN’s “The Lead” as well as “State of the Union,” responded by mockingly noting how he “can’t imagine” what it would be like if “someone in government” used Twitter to target their political opponents, an apparent reference to former President TrumpDonald TrumpThe Memo: How the COVID year upended politicsBiden seeks his moment with pandemic address A year with the coronavirus: How we got hereMORE’s frequent use of the platform for such purposes.

Tapper’s tweet prompted a second back-and-forth between the two men, with Cornyn asking if Tapper “approve[s]” of such behavior.

“For a half decade youve been as quiet as a church mouse about twitter attacks from someone with far more power than an associate attorney general,” the CNN host shot back. “The question isnt about my standards. Its about where yours have been.”

The Hill has reached out to CNN for comment.

Tapper has increasingly sparred with GOP lawmakers over their support for the former president and in particular his false claims about the 2020 election results in the weeks leading up to the deadly riot at the Capitol in January.

In late January, Tapper fiercely criticized Rep. Guy Reschenthaler (R-Pa.) over the issue, telling the Republican lawmaker that he would personally question the patriotism of anyone who defended their actions regarding efforts to overturn the 2020 election results in response to the deadly attack on Congress.

“I question the patriotism of anyone who spreads election lies, signs on to a mendacious Supreme Court lawsuit, and votes to disenfranchise millions of voters including your own!! especially with blood on the floor after a terrorist attack,” he told the GOP lawmaker that month, adding: “You betrayed your own voters.”
