Miley Cyrus just won’t quit trolling Sen. Tom Cotton (R-AK).

On Thursday, Cyrus instructed her nearly 20 million Twitter followers to call Cotton’s Washington, D.C. office to lodge complaints over the Senator’s support for Indiana’s Religious Freedom Restoration Act.

“Let’s stir some sh*t up,” Cyrus tweeted, along with the number of Cotton’s office.

Just a couple of hours after that tweet, Cyrus followed up with another:

Thursday night, Cyrus issued another tweet, claiming responsibility and gloating over the fact that Sen. Cotton’s voicemail box was completely full and the line apparently turned off:

Breitbart News confirmed that Sen. Cotton’s mailbox was indeed full, before the message was replaced by another saying the office would be closed for Good Friday. The message notes that the office will reopen Monday during regular business hours.

Cyrus’ social media vendetta against Cotton appeared to stem from an interview the freshman Republican gave to CNN this week, in which he said that critics of Indiana’s law should adopt “perspective” about the new legislation.

“I think it’s important we have a sense of perspective,” Cotton said during the interview. “In Iran they hang you for the crime of being gay.”

Cotton was asked by ABC News on Thursday about the comments made by the singer. The Senator did not mention Cyrus’ name, instead reiterating his belief in the importance of religious freedom.

“In fact it goes way back past our founding – that’s one of the reasons the puritans and the pilgrims came here,” Cotton told the outlet. “So I’ll always stand up to defend religious freedom. I’ll also always stand up to keep America safe.”

Indiana’s religious freedom law, first signed by Gov. Mike Pence last month, was amended on Thursday to include specific language prohibiting businesses from discrimination based on sexual orientation. The law, which prohibits the state and federal government from unduly burdening individuals’ right to exercise their religion, has been criticized by celebrities and media figures for being anti-gay.
