WATCH: Trump claims he likes Taylor Swift's music '25 percent less' after she comes out in support of Dems

President Donald Trump told reporters Monday that he likes Taylor Swift's music "25 percent less now" after the country-pop singer came out in support of Tennessee Democrats — and against the Republican woman running for office.

The comments were first reported by Reuters' Jeff Mason as the president made them on the White House's South Lawn.

In a Sunday Instagram post, the normally apolitical Swift wrote that the voting record of Marsha Blackburn, the Tennessee congresswoman running for Senate, " appalls and terrifies" her.

"Her voting record in Congress appalls and terrifies me," the singer wrote. "She voted against equal pay for women. She voted against the Reauthorization of the Violence Against Women Act, which attempts to protect women from domestic violence, stalking, and date rape. She believes businesses have a right to refuse service to gay couples. She also believes they should not have the right to marry."

She then endorsed Democrats Phil Bredesen for Senate and Jim Cooper for the House of Representatives.

In a press gaggle on the White House lawn Monday, Trump weighed in on Swift's comments first by congratulating Blackburn for doing a "very good job" and leading Bredesen in the polls before turning his attention to the singer.

"I'm sure Taylor Swift has nothing — doesn't know anything about her," the president said. "And let's say that I like Taylor's music about 25 percent less now."

Trump wasn't the only one disappointed by Swift's endorsement of Democrats. White nationalists who once lauded the singer as their "Aryan goddess" whined about her being a "traitor" to their cause.

"Stupid b*tch doesn’t respect the Trump curse,” an alt-right 4chan user wrote. “She has to learn the hard way.”
