President Trump sparked a tweetstorm Friday when he cracked a sex joke about the late Supreme Court Justice Antonin Scalia during a Medal of Freedom presentation at the White House — with his widow Maureen McCarthy seated in the audience.

After reading an introduction that noted the Scalias had nine children, the president said: “You were very busy. Wow. I always knew I liked him” as some in the crowd chuckled.

Wags were quick to react on Twitter.

“Congrats on the sex, Scalia family,” blogger Parker Molloy tweeted.

“Just when you think Trump can’t be any grosser, he has to comment on a dead man’s sex life,” wrote singer-songwriter Holly Figueroa O’Reilly.

“Thank you Mr. President for the image of Antonin Scalia having sex,” added actor and comedian Ike Barinholtz.
