Pharrell Threatens To Sue Over Use Of 'Happy' At IN Trump Rally

INDIANAPOLIS, IN — Pharrell Williams isn't happy with President Donald Trump. The musician is threatening to sue Trump, who continued with "Make America Great Again" rallies in Indiana and Illinois the same day a gunman murdered 11 people in a mass shooting at a Pittsburgh synagogue. As some questioned Trump's justification for keeping his schedule despite the horror in Pittsburgh, Williams has issued a cease-and-desist letter over the use of his hit song "Happy" during an event in Indianapolis.

"On the day of the mass murder of 11 human beings at the hands of a deranged 'nationalist,' you played his song 'Happy' to a crowd at a political event in Indiana," Williams' attorney Howard King said in the letter. "There was nothing 'happy' about the tragedy inflicted upon our country on Saturday and no permission was granted for your use of this song for this purpose."

King said the unauthorized use of the song, which appeared on the "Despicable Me 2" soundtrack, constitutes copyright infringement.

Pharrell isn't the first artist to slam Trump for using his music without permission. The Rolling Stones, the O’Jays, Adele and Queen have also asked the president to stop using their songs, according to WGN.

While speaking at a Future Farmers of America event in Indianapolis Saturday, Trump said he would still make a planned stop at a rally in downstate Illinois later in the day.

"We don't want to let people that are evil change our lives," Trump said. "I will go to Illinois. And, we'll keep our schedule the way it's supposed to be."

During a "Make America Great Again" rally at the Southern Illinois Airport hours later, Trump stumped for U.S. Rep. Mike Bost, a first-term southern Illinois Republican who is running against Brendan Kelly in the 12th Congressional District. He also spoke about the Pittsburgh shooting, calling it an "evil anti-Semitic attack."
