Immigration officials are pushing back on a British punk singer’s claim he was denied entry into the U.S. because of his impersonation of President Trump.

Customs and Border Protection (CPB) officials told Entertainment Weekly that Peter Bywaters of the band Peter and the Test Tube Babies was denied entry because he did not have a proper visa to perform in the U.S.

“The claim that he was refused entry to the United States because he mocked the president of the United States, that is absolutely not true,” Jaime Ruiz told the publication.

Bywaters told Team Rock he was on his way to perform with his band at the Punk Invasion Festival in Southern California when U.S officers confronted him with video and photos of him impersonating Trump during the band’s German tour last year.

Bywaters said he was interrogate for six hours, and his phone and passport were confiscated before he was escorted to a seat on a plane back to the U.K.

Despite Bywater’s absence, the rest of his band performed in Orange Country, Calif. at the festival on Saturday, according to BBC.
