A man with a baseball bat attacked two staffers of Virginia Congressman Gerry Connolly on Monday.

Mr. Connolly - a Democratic House representative - said that one of the victims was an intern on her first day on the job.

Both staff members were treated at the hospital for injuries that did not pose a life-threatening threat.

In 2022, there were approximately 7,500 investigations into threats made against members of Congress.

In a tweet, Connolly, a member of the House of Representatives since 2009, stated that a person had entered his district office in Virginia, on Monday morning, "and asked me for me, for me before committing an act of violence against two members of my staff."

He added that the "thought that someone would take advantage of my staff's accessibility to commit an act of violence is unconscionable and devastating."

In an interview with CNN, Mr. Connolly said that the assailant had struck a senior aide in the head with a metal bat and hit an intern - who was on her first day on the job - on the side.

"He was filled with out-of-control rage," Mr Connolly said.

In its own statement, US Capitol Police identified the suspect as 49-year-old Virginia resident Xuan Kha Tran Pham, who now faces one count of aggravated malicious wounding and one count of malicious wounding.

CBS, the BBC's US partner, has reported that a man with the same name as the suspect last year filed a handwritten lawsuit against the CIA, seeking $29m (£23m) for "brutally torturing" him "from the fourth dimension". The justice department sought to dismiss the case earlier this year.

Mr. Connally's congressional district is mostly comprised of Fairfax County, a suburb of Washington DC in northern Virginia.

The BBC has reached out to police in Fairfax for comment.

US Capitol Police, which is responsible for protecting members of Congress, has warned that threats against lawmakers have been rising in recent years.

In 2022, the force investigated 7,500 potential threats, though that was down from 9,600 in 2021. In 2017, the figure stood at less than 4,000.

"One of the biggest challenges we face today is dealing with the sheer increase in the number of threats against Members of Congress - approximately 400% over the past 6 years," US Capitol Police Chief Tom Manger testified in April. "Over the course of the last year, the world has continuously changed, becoming more violent and uncertain."

The issue of lawmaker safety was starkly highlighted in October when Former House Speaker Nancy Pelosi's husband Paul was seriously injured by a hammer-wielding suspect at the couple's home in San Francisco. Speaker Pelosi was not at home at the time.
