Kash Patel’s erratic behavior at the FBI could cost him his job, including what his colleagues describe as unexplained absences and excessive drinking, which have alarmed colleagues and his security detail, The Atlantic reports.

“Several officials told me that Patel’s drinking has been a recurring source of concern across the government. They said he is known to drink to the point of obvious intoxication, in many cases at the private club Ned’s in Washington, D.C., while in the presence of White House and other administration staff. He is also known to drink to excess at the Poodle Room in Las Vegas, where he frequently spends parts of his weekends.”
