Rep. Matt GaetzMatthew (Matt) GaetzBipartisan senators to hold hearing on 'toxic conservatorships' amid Britney Spears controversy Eric Trump lawyer in New York attorney general's fraud case quits Republicans keep distance from 'Justice for J6' rally MORE is taking his advocacy for the "Free Britney" movement a step further — speaking at a demonstration protesting Britney Spears's conservatorship during a critical court hearing for the singer.

The Florida Republican, who is under investigation over potential sex trafficking violations, was eyed among the crowd outside a Los Angeles courthouse on Wednesday for a hearing in which a judge was expected to rule on whether Spears could choose her own attorney in the conservatorship case.

The 39-year-old "Toxic" singer told a Los Angeles Superior Court judge last month that she was "traumatized" by the conservatorship, which was put in place 13 years ago following her public mental health struggles and is headed by her father, Jamie Spears.

"Britney's been abused by the media, she's been abused by a grifter father, and she has been abused by the American justice system," Gaetz said in a video of his remarks.

"We need to come together and create federal laws of action, a federal change in the law that will free Britney and the millions of Americans who are impacted by a corrupt guardianship system that empowers people to take advantage of the weak."

"There's a lot that still divides us, but one thing we can all agree on is that Jamie Spears is a dick," Gaetz said to cheers.

Gaetz was one of four GOP lawmakers who earlier this month invited Spears to testify before Congress about the conservatorship. In a letter to the performer, the members of Congress said that she had been "mistreated by America’s legal system."
