The campaign office of former President Donald Trump in Auburn, Virginia, was broken into over the weekend, local authorities announced on Monday, as their investigation into the incident continues.

The Loudoun County Sheriffs Office is seeking a suspect in connection to the burglary and has released still images of a white male suspect wearing dark clothing, a hat and a backpack, recovered from the offices surveillance footage while asking the public to assist in their probe.

Authorities were alerted to the break-in on Sunday evening and deputies headed to the location, which is also the headquarters of the Virginia 10th District Republican Committee.

It is rare to have the office of any political campaign or party broken into, Sheriff Mike Chapman said in a statement . We are determined to identify the suspect, investigate why it happened, and determine what may have been taken as well as what may have been left behind.

HuffPost has reached out to Trumps campaign for comment on the incident.

Meanwhile, the FBI is investigating a number of cyber attacks which they suspect Iran is behind, including one targeting longtime GOP operative Roger Stone, a Trump ally, according to The Washington Post . Stones email account appears to have been compromised by the hackers, who then used it to send messages to people in the Trump campaign, the Post reported. The FBI on Monday confirmed it is investigating a cyber attack targeting Trumps campaign without offering further details.

Hackers also took aim at staffers from the now-defunct Biden-Harris campaign, but their phishing attempts appeared to have been unsuccessful, sources told the Post.

The former president spent Monday evening talking to billionaire Elon Musk in a live event hosted on X, formerly Twitter, during which he spread falsehoods and attacked his main rival, Vice President Kamala Harris .
