3rd Member of Congress Receives Death Threat Over Health Care Law

Source: USA Today
The Associated Press reports that a California man was arrested for allegedly making threatening phone calls to House Speaker Nancy Pelosi.
The AP based its report on sources. USA TODAY's Matt Kelley is checking into it.
The AP said:

Several federal officials say the man made dozens of calls to Pelosi's homes in California and Washington, as well as to her husband's business office, reciting her home address and saying if she wanted to see it again, she would not support the health care overhaul bill that was recently enacted. 

If confirmed, it would be the third time since the health care bill passed that someone has been arrested for threatening a member of Congress. As USA TODAY's Kathy Kiely wrote in today's paper, a 63-year-old man was arrested for allegedly calling and leaving numerous death threats at the office of Sen. Patty Murray, D-Wash. Last week, the FBI arrested a man who allegedly threatened the life of Virginia Rep. Eric Cantor, the No. 2 House Republican.
More information to come as we get it.
Updated at 5:30 p.m. ET. USA TODAY's Kevin Johnson confirms that an arrest was made in the Pelosi case. He writes:

U.S. Capitol Police spokeswoman Kimberly Schneider confirmed the arrest, saying the investigation and arrest was a "coordinated effort'' between the FBI and Capitol Police. 

Updated at 5:43 p.m. ET. From Matt Kelley:

Pelosi has been the subject of threats before. In 2006, authorities arrested a Los Angeles man after he mailed envelopes filled with white powder and threatening messages to Pelosi and other political and entertainment figures. The powder turned out to be harmless. Chad Conrad Castagana was convicted in 2008 and sentenced to five years' probation.

Updated at 6:42 p.m. ET. San Francisco FBI spokeswoman Patti Hansen identified the suspect as Gregory Guisti, 48. He was arrested without incident in San Francisco at 12:15 p.m., and he is scheduled to make his initial court appearance at 9:30 a.m. Thursday, Hansen said. She declined to elaborate on the allegations against Guisti.
