[Updated 1:49 p.m.] A Richmond police spokeswoman confirmed to CNN that a bullet was fired at Rep. Eric Cantor's campaign office.
"We are investigating the circumstance surrounding it," police spokeswoman Karla Peters said. Cantor disclosed the incident to reporters Thursday.
Cantor also accused Democrats of "fanning the flames" of violence by using threats that have been made against Democratic members "as political weapons." Democrats immediately hit back against Cantor's accusation, repeating their allegations that Republicans are at fault.
"We disagree with the charge made by Rep. Cantor today that Democrats are using acts of violence for political gain," said Brad Woodhouse, a spokesman for the Democratic National Committee.
"Let's be clear: calling on Republican leaders who have contributed in part to this anger by wildly mischaracterizing the substance and motives of health reform to condemn these acts is entirely appropriate. Instead distracting from the issue with more attacks, we would again ask Mr. Cantor and other Republicans ... to ratchet down the rhetoric, condemn deplorable behavior and find ways to disagree on these issues without the charged rhetoric that we've been hearing from Republican leaders."
[Posted at 12:33 p.m.] Rep. Eric Cantor, the number two Republican in the House of Representatives, said Thursday that a bullet had been shot through a window at his district office in Richmond, Virginia. He also said he had received threatening messages.
He said he would not publicly release the messages out of concern that doing so would only incite further violence.
He also accused Democratic National Committee Chairman Tim Kaine and Rep. Chris Van Hollen of Maryland - a member of the Democratic House leadership - of "fanning the flames" of violence by using threats that have been made against Democratic members "as political weapons."
"Legitimate threats should be treated as security issues, and they should be dealt with by the appropriate law enforcement officials," Cantor told reporters on Capitol Hill. "It is reckless to use these incidents as media vehicles for political gain. ... Enough is enough. It has to stop."
Cantor, who is Jewish, said he had received numerous threats throughout his career both on account of his religion and his position in the GOP leadership.
More than 10 Democrats have reported trouble since the weekend health care vote, House Majority Leader Steny Hoyer, D-Maryland, told reporters on Wednesday.
Windows have been smashed at Democratic offices in at least three states, and federal agents are investigating whether a cut gas line at the home of a Virginia congressman's brother was related to the lawmaker's yes vote.
Democratic congressional leaders have demanded Republicans join them in condemning a spate of threats and vandalism that has followed Sunday's vote onÂ a sweeping overhaul of the U.S. health care system.
