MSNBC's "Morning Joe" saw a 70 percent jump in viewers Friday compared to the second quarter of 2017, as more people tuned into the morning show the day after President Trump attacked co-hosts Mika Brzezinski and Joe Scarborough on Twitter.

According to the Wrap, 1.7 million people watched "Morning Joe" on Friday morning, when Scarborough and Brzezinski responded to Trump's tweets calling Scarborough "psycho" and Brzezinski "low IQ crazy."

The show finished first in the cable news morning shows both in total viewers and the 25-54 age demographic, with 408,000 viewers.

From April through June, "Morning Joe" averaged 997,000 total viewers.

Trump posted a pair of tweets Thursday morning criticizing the "Morning Joe" co-hosts.

"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 president said on his Twitter account.

Trump's comments were criticized by lawmakers on both sides of the aisle, and Scarborough and Brzezinski delayed a Fourth of July vacation to appear on their show Friday morning and respond to the president's tweets.

Scarborough said during the appearance that he received a phone call from a senior Republican congressman several months ago who told him Trump made disparaging comments about the couple to roughly 20 lawmakers during an event at the White House.

The pair also wrote an op-ed for the Washington Post, published Friday, saying that White House officials warned them about a negative story the National Enquirer was planning to publish about them that would be pulled if they asked Trump for help.

Jared Kushner, the president's son-in-law and White House senior adviser, was reportedly one of the staffers who threatened Scarborough and Brzezinski with the negative National Enquirer story unless they contacted Trump.
