WEST PALM BEACH, Fla. — At least five Democratic members of Congress from Connecticut were targeted by bomb threats on their homes Thursday, the lawmakers or their offices said.

Sen. Chris Murphy and Reps. Jim Himes, Joe Courtney, John Larson and Jahana Hayes all reported being the subject of such threats. Police who responded said they found no evidence of explosives on the lawmakers’ properties.

There was no immediate word whether Rep. Rosa DeLauro, the fifth Democratic House member from the state, and Connecticut’s other Democratic senator received threats.

The bomb threats against Democrats happened a day after a number of President-elect Donald Trump ‘s most prominent Cabinet picks and appointees reported that they had received such threats, as well as “swatting attacks,” in which perpetrators initiate an emergency law enforcement response against a victim under false pretenses.

Murphy’s office said his Hartford home was the target of a bomb threat, “which appears to be part of a coordinated effort involving multiple members of Congress and public figures.” Hartford Police and U.S. Capitol Police determined there was no threat.

Hayes said the Wolcott Police Department informed her Thursday morning that it had received “a threatening email stating a pipe bomb had been placed in the mailbox at my home.” State police, U.S. Capitol Police, and the House sergeant at arms were notified, Wolcott and state police responded “and no bomb or explosive materials were discovered.”

Courtney’s Vernon home received a bomb threat while his wife and children were there, his office said.

The threats follow an election season marked by violence. In July, a gunman opened fire at a Trump rally in Butler, Pennsylvania, grazing him in the ear and killing one of his supporters. The Secret Service later thwarted a subsequent assassination attempt at Trump’s West Palm Beach, Florida, golf course when an agent spotted the barrel of a gun poking through a perimeter fence while Trump was golfing.
