A man has been arrested for allegedly threatening House Speaker Nancy Pelosi, the FBI announced Wednesday.
FBI spokesman Joseph Schadler said the arrest occurred in San Francisco, California, where Pelosi's home district is located. He identified the suspect as Gregory L. Giusti, but no further details were immediately available.
Â Pelosi was a leading figure in Democratic efforts to win congressional approval of a new health care bill.
Threats against U.S. senators and representatives increased as Congress completed work last month on the health care bill, which was unanimously opposed by Republicans. In addition, conservative activists around the country protested the bill.
Most of the reported threats were against Democrats, though there were some against Republicans.
On Tuesday, the Justice Department announced the arrest of a 64-year-old Washington state resident for allegedly issuing death threats against Democratic Sen. Patty Murray of Washington, who supported the health care bill.
A department statement said the suspect, identified as Charles Alan Wilson of Selah, Washington, made the threats in phone messages to Murray's office between March 22 and April 4.
Wilson allegedly stated that Murray "had a target on her back" and that he wanted to kill her, according to the statement, which said the threats were in response to congressional passage of the new health care bill.
Threatening a federal official is punishable by up to 10 years in prison and a $250,000 fine, the Justice Department statement said.
