Bruce Reinhart acted for several employees of the billionaire pedophile before he sanctioned the 'unannounced' search on Mar-a-Lago yesterday.
He left the local US Attorney's office over a decade ago to set up a private practice and help staff members including his Lolita Express pilots and his scheduler.
He was accused in a lawsuit of breaking the Justice Department's policies by using information from his previous job to benefit in the private sector, which he denied.
Meanwhile Reinhart was also revealed to have donated to Barack Obama's campaign in 2008 and Jeb Bush's when he ran against Trump in 2015.
The FBI searched Trump's estate as part of a probe into whether he took classified records from the White House to his Florida mansion.
The ex-president revealed the raid in a lengthy statement and said the Feds broke into a safe at his home as they hunted the documents.
