Last week, House Democrats were meeting behind closed doors to try to find the magic number of 216 to pass health care. This week -- after its passage -- the caucus met about their personal safety.
Since this weekend's historic vote, at least 10 Democratic representatives have received verbal and written threats. The House Seargent at Arms, FBI, and U.S. Capitol Police all met with House members "to address security concerns."
One of the offices that has received multiple threatening and vulgar messages is Rep. Bart Stupak (D-MI). Stupak's yes vote on health care was key to getting the Democrats over the 216 mark.
One anonymous caller to Stupak's office said, "There are millions of people across the country who wish you ill and all of those thoughts projected on you will materialize into something that's not very good for you."
Another man who leaves his address on the recording said, "You're a cowardly punk, Stupak. That's what you are. You and your family is scum. You oughta fill your pockets with lead and jump in the Potomac."
Stupak's office also received a faxed picture of a noose. There are reports of Majority Whip Clyburn's office receiving a similar fax, as well as threatening phone calls to his home. When asked about the calls, Clyburn said: "My wife is pretty used to this. She didn't share all the conversations with me. We turned over the phone numbers... For five years before I came to Congress, I was under constant state protection so we know how to do this."
Other members of Congress who have received threats include Rep. Betsy Markey (D-CO) and Rep. John Boccieri (D-OH). Both are representatives who flipped their health=care reform votes from no to yes.
First Read and NBC News have previously reported on the vandalism involving the district offices of Rep. Louise Slaughter (D-NY) and Rep. Gabrielle Giffords, as well as the incident at Rep. Tom Perriello's (D-VA) brother's home.
