The first lady and a White House spokeswoman on Thursday defended President Trump’s harsh Twitter attack on MSNBC’s Mika Brzezinski — which critics slammed as sexist.

“As First Lady has stated publicly… when her husband gets attacked, he will punch back 10 times harder,” read a statement from the office of Melania Trump, who pledged that as first lady she would launch a war on cyberbullying.

Spokeswoman Sarah Sanders also came to her boss’ defense, saying Trump “is a president who fights fire with fire.”

“Look, I don’t think the president’s ever been someone who gets attacked and doesn’t push back,” she said on Fox News.

Sanders also said that Brzezinski and co-host and hubby Joe Scarborough had insulted her on “Morning Joe.”

“People on that show have personally attacked me many times,” she said.

Trump attacked the pair earlier Thursday.

“I heard poorly rated @Morning_Joe speaks badly of me (don’t watch anymore). Then how come low I.Q. Crazy Mika, along with Psycho Joe, came to Mar-a-Lago 3 nights in a row around New Year’s Eve, and insisted on joining me. She was bleeding badly from a face-lift. I said no!” the commander in chief tweeted.
