Facing backlash for a tweet in which he appeared to intimidate Michael Cohen by accusing him of marital infidelity, Rep. Matt Gaetz is now urging supporters to “leave the Cohen family alone.”

“Regardless of disagreements, family members should be off-limits from attacks from representatives, senators & presidents, including myself,” Gaetz tweeted Wednesday night.

On Tuesday, on the eve of President Donald Trump’s former fixer’s appearance before the House Oversight Committee, the Florida Republican appeared to try to intimidate Cohen by asking if his wife knew about his “girlfriends.”

I’ve personally apologized to @MichaelCohen212 4 referencing his private family in the public square. Regardless of disagreements, family members should be off-limits from attacks from representatives, senators & presidents, including myself. Let’s leave the Cohen family alone. — Matt Gaetz (@mattgaetz) February 28, 2019

Republicans had sought to undermine Cohen’s credibility and cast doubt on his testimony against the president before the Oversight hearing on Wednesday. But some critics said Gaetz’s threat went further, and might have constituted witness tampering.
