Gaherty did not conceal his phone number, allowing U.S. Capitol Police to easily trace the source of the calls via data from T-Mobile and TracFone.

"Further investigation by USCP agents revealed that GAHERTY used the same phone number to leave at least four racist voicemails threatening to kill or assault Congresswoman Waters between August and November 2022, including a threat to 'cut your black ass throat' n----" on August 8, 2022," the USCP said in an affidavit.

Gaherty is also accused of leaving similarly threatening messages for at least two other congresswomen of color.

At a Monday detention hear, bond was set at $100,000, and court records says bond was later executed and Gaherty was expected to be released.

A request to an attorney representing Gaherty was not immediately returned.
