Donald Trump says "I hate Taylor Swift!"

Former President Donald Trump took aim at Taylor Swift in a Truth Social post Sunday, declaring his distaste for the superstar after she endorsed his opponent, former Vice President Kamala Harris. 

"I HATE TAYLOR SWIFT!" Trump wrote in the post.

His announcement emerged online less than a week after Swift revealed publicly for the first time her plans to vote for Harris, the Democratic nominee in this year's presidential election. Her endorsement followed the first debate on Sept. 10 between Trump and Harris, which saw the two candidates face off during a televised showdown in Philadelphia that covered issues like abortion, immigration, the economy and foreign policy.
