An Allegheny County man who is running as a Democrat for the U.S. Senate has been arrested on allegations that he made threats against President Donald Trump and a member of Congress, according to federal authorities.

The Federal Bureau of Investigation confirmed that Raymond Chandler was taken into custody Friday morning in Pittsburgh with assistance from the United States Secret Service.

Court documents filed in the U.S. District Court for the Western District of Pennsylvania outline the alleged threats. According to an affidavit, Chandler left a voicemail on April 18 for an unidentified member of Congress that included violent language about harm to the lawmaker and their family.

Prosecutors say Chandler followed up on April 29 with another voicemail, in which he allegedly urged the recipient to assassinate the president. The filing also states that his messages included harsh personal criticisms of Trump.

Authorities say congressional staff ultimately contacted law enforcement as the messages escalated in tone and frequency, with threats also referencing members of Congress and immigration authorities.

Just hours before his arrest, Chandler reportedly posted a campaign video announcing his intention to challenge John Fetterman in the 2028 election. His campaign platform includes progressive policy positions such as higher taxes on billionaires, expanded social programs, regulation of major technology companies, and abolishing ICE.

Separately, federal prosecutors have brought charges against Cole Allen, 31, of Torrance, California, in connection with an alleged attempted attack at the Washington Hilton during the White House Correspondents’ Dinner.

According to the U.S. Department of Justice, Allen faces charges including attempted assassination of the president, use of a firearm during a crime of violence, and transporting a firearm across state lines.

“He attempted to assassinate the president of the United States, Donald J. Trump,” Assistant U.S. Attorney Jocelyn Ballantine told the court. “We are asking the court to preventatively detain Mr. Allen.”

U.S. Attorney Jeanine Pirro said during a press conference that additional charges could be filed as the investigation continues.

“But make no mistake, this was an attempted assassination of the President of the United States, with the defendant making clear what his intent was,” Pirro said. “And that intent was to bring down as many of the high ranking Cabinet officials as he could. This is the kind of situation that we cannot tolerate.”

The cases remain under investigation, and authorities have not indicated any connection between the two incidents.
