Hunter Biden’s T-shirt-clad lawyers Abbe Lowell and Kevin Morris were evacuated from their luxury Wilmington, Del., hotel Wednesday night after a fire alarm went off hours after proceedings in the first son’s federal gun trial wrapped up for the day.  

Trial witnesses and dozens of other guests were forced out of their rooms and down the fire stairs as piercing alarms blared throughout the downtown Hotel Du Pont at 9:30 pm. 

Hunter and wife Melissa Cohen have been discreetly staying at the $400-per-night hotel this week but were nowhere to be seen among the crowd of evacuees standing in the rain outside the 111-year-old building. 

Morris refused to comment when asked by The Post if the couple had been whisked away by the Secret Service.

Evacuees were ushered through a tunnel into the neighboring DECO Food Hall while firefighters dealt with what appeared to be smoke billowing from the Du Pont kitchen. 

The apparent emergency was over by 10:20 pm and hotel guests returned to their rooms or the hotel bar. 

The Wilmington Fire Department did not respond to The Post’s request for comment. 

A person who answered the listed phone number on the hotel website told The Post she was not at the hotel and was unaware of any fire.

The 53-year-old first son’s trial will resume Thursday at 9 a.m., with jurors continuing to hear testimony from Gordon Cleveland, an employee at the Delaware gun store where Hunter purchased a .38 caliber revolver while allegedly in the throes of a crack cocaine addiction.

Hunter is accused of lying about his illegal drug use on a federal form when he purchased the firearm. 

He faces a maximum of 25 years in prison if convicted of the three felony counts against him.
