'Drunk' Secret Service agent groped Kamala campaign worker's chest and tried to assault second victim before being booted out of party and falling asleep in hotel's hall

A Secret Service agent accused of sexually assaulting a staffer for Vice President Kamala Harris in Wisconsin was ‘fall-down drunk’ when he forcibly groped her.

The unidentified man is now also under investigation for attempting to grab a second staffer, DailyMail.com has learned.

‘He may have tried to grope another women present too,’ the source with knowledge of the incident said, and added that this is part of the investigation.

Video showing the agent collapsed in the hallway of a hotel, where the alleged sex assault took place early, the source tells DailyMail.com.

The source revealed that the agent was already wasted when he first approached a group of campaign staffers that night in a restaurant/bar in Green Bay, Wisconsin, where the campaign was doing advance work for an upcoming Harris campaign event.

In the end the event was canceled as the campaign chose to hold a rally in Atlanta instead.

The night of the alleged assault was the last day in town for the advance planners, who were due to head out the following morning.

After they left the bar the group of staffers went back to the room of the woman who was assaulted to continue partying. The agent went with them.

‘There’s no misunderstanding about what happened,’ the source explained. ‘It’s just him being a drunk dufus at a bar. 

'The staff came in and recognized him from being in the same orbit, and they allowed him to join the group. 

'In his drunken state, he started making advances. This agent is 100 percent at fault.’ 

He followed the woman back to her hotel room, where he allegedly came at her and grabbed her chest, the source said.

‘He was a hot mess and at some point wound up on the hotel hallway floor,’ the source said. ‘There’s some video of him being intoxicated on the floor. He was annihilated.’

The agent was sent back to Washington, D.C. 

'The U.S. Secret Service Office of Professional Responsibility is investigating a misconduct allegation involving an employee,' a Secret Service spokesman told Real Clear Politics.

The source told DailyMail.com: ‘He’s going to be investigated, he’s no longer going to be working for the VP, and his career will be adversely impacted.’ 

The source described the victim as a low-level staffer in her 20s, who doesn’t want her identity to leak out.

‘The victim’s okay, but deeply concerned at not having her name attached to this,’ the source said. ‘This is not what she wants to be known for.’

Neither The White House nor the Secret Service immediately responded to DailyMail.com's request for comment. 

The new report is further embarrassment for the agency following two assassination attempts on former President Donald Trump.

 News of the incident comes on the same day the Senate released a report revealing a series of failures by the Service that ultimately allowed would-be assassin Thomas Crooks to successfully fire sshoots at Trump, clipping his right ear.

One supporter at the rally in Butler, Pennsykvania, was killed and two more sseriously injured. 

Another troubling finding from the bipartisan investigation was how technical issues downed Secret Service drones during the July 13.

It took several hours to get the drones back up and running – and the agent responsible for the drone operations only had three months of experience with the equipment.     

The report released on Wednesday concluded that the failures ahead of the rally were 'foreseeable, preventable, and directly related to the events resulting in the assassination attempt that day.'

The second assassination attempt against Trump came on September 15 when gunman Ryan Routh hid in bushes outside the former president's golf club in West Palm Beach, Florida.

As Trump walked down the fifth fairway, Secret Service agents went ahead to the sixth hole where an agent saw Routh's rifle barrel.

Agents shot at him but he got away and was later arrested in Port St. Lucie, Floriday, 45 miles north of the scene.

Routh, 58, is now facing charges of attempting to assassinate a presidential candidate, assaulting a federal officer and possessing a firearm in furtherance of a crime of violence.
