A background investigation into John McEntee — who was fired and escorted out of the White House earlier this week — found that he often gambled, The Washington Post reported Thursday.

The investigation found that McEntee had in the past bet tens of thousands of dollars at a time, and the habit created potential security risks, two people familiar with his departure told the Post.

The Post reported that there was no evidence McEntee's habits were illegal, but aides were reportedly worried he could be subject outside influence.

McEntee had worked with Trump since early in his presidential campaign. His duties in the White House included making sure Trump had markers to sign autographs and ensuring the White House clocks were adjusted this past weekend for daylight saving time.

The Trump campaign announced on Tuesday that McEntee is rejoining the organization as a senior adviser.

McEntee’s departure was first reported on the heels of Trump firing Secretary of State Rex TillersonRex Wayne TillersonTillerson: 'We squandered the best opportunity we had on North Korea' State Department sets up new bureau for cybersecurity and emerging technologies Lawmakers express concern about lack of young people in federal workforce MORE as part of a spate of staff shake-ups.

McEntee is also the latest in a series of White House staffers who have left following a change to the security clearance policy.

Dozens of staffers, including senior adviser Jared Kushner, have in recent weeks had their clearances downgraded from "top secret" to "secret." A number of those individuals have reportedly been reassigned or fired since the changes.
