Cardi B hit back at critics who claim she was paid to appear at a Kamala Harris‘ campaign rally in Milwaukee, Wisconsin and endorse the vice president.

‘I didn’t get paid a dollar and that’s on my three!!’ she wrote on social media in response to a question from conservative show host Candace Owens.

‘I actually came out of pocket for glam and travel because it’s somewhere I wanted to be,’ she said.

Addressing Owens, Cardi B added, ‘Like please girl you know damn well I’ll argue you down about politics FOR FREE.’

Other celebrities who endorsed Harris and participated in campaign events included Beyonce, Lady Gaga, Katy Perry, Eminem, Lizzo, and Megan Thee Stallion.
