Washington, D.C., police responded around 10 p.m. to a report of a shooting at a home linked in public records to U.S. District Judge Tanya Chutkan. But officers quickly found out that no shooting happened, the Metropolitan Police Department said Monday.

Chutkan has received numerous threats since she was assigned Trump’s case last year. In August, a Texas woman was arrested after calling the courthouse and threatening to kill Chutkan and other officials. Investigators traced her phone number and she later admitted to making the threatening call, according to court documents.

Sunday’s incident comes after a spike in swatting directed at high-profile public officials over the holidays. Swatting refers to prank calls made to emergency services designed to draw a police response, especially from a SWAT team, to the homes of unsuspecting victims, putting them at risk.

Those whose homes have been targeted include Republican U.S. Rep. Marjorie Taylor Greene of Georgia and Maine Secretary of State Shenna Bellows, a Democrat who removed Trump from the state’s presidential primary ballot under the Constitution’s insurrection clause.

State capitols and courthouses in several states were also targeted by bomb threats last week, prompting lockdowns and evacuations. No explosives were found and the FBI called the threats a hoax.

U.S. Atty. Gen. Merrick Garland on Friday called the spike in threats “deeply disturbing” in remarks ahead of a private meeting with top Justice Department leaders to address violent crime.

“These threats of violence are unacceptable. They threaten the fabric of our democracy,” he said.
