The House Foreign Affairs Committee has placed restrictions on the trips Rep. Dana Rohrabacher, R-Calif., can take overseas using committee funds and on the hearings a subcommittee he chairs can hold, according to a report.

Rohrabacher has come under scrutiny for his ties to Russia and frequent defenses of Moscow. In 2012, the FBI warned Rohrabacher Russian spies were attempting to recruit him as an "agent of influence," the New York Times reported in May.

In addition to his ties to Russia, Rohrabacher has also raised eyebrows for his relationship with Julian Assange, founder of WikiLeaks.

The California Republican visited Assange at the Ecuadorean Embassy in London over the summer, but had to pay for the trip himself, according to The Daily Beast.

Rohrabacher had asked to use committee money to pay for his travel to London, but his request was denied, a source told The Daily Beast.

"His committee travel and hearing requests were curtailed following news accounts of his outside-the-box interest in Russia," Ken Grubbs, Rohrabacher's communications director, told The Daily Beast.

In addition to the restrictions on the congressman's use of committee funds, GOP leaders have also intervened in Rohrabacher's subcommittee hearings.

As chairman of the Subcommittee on Europe, Eurasia and Emerging Threats, Rohrabacher wanted to hold a hearing last year on the 2012 Magnitsky Act, during which he planned to hold a "show trial" of Bill Browder, who pushed for the law, and show a pro-Kremlin propaganda film that sought to damage Browder's reputation.

The congressman obtained the movie from a top official to Russian President Vladimir Putin during a meeting in Russia.

At the hearing, Rohrabacher wanted to have the director of the film and a Russian lawyer, Natalia Veselnitskaya, testify as witnesses.

Veselnitskaya attended a meeting at Trump Tower last year with Donald Trump Jr., then-campaign chairman Paul Manafort, and Jared Kushner, President Trump's son-in-law.

House Foreign Affairs Committee Chairman Ed Royce, R-Calif., heard about the plans for the hearing, and it ultimately never took place.

In addition to the proposed hearing with Veselnitskaya, Rohrabacher also wanted to hold a hearing examining Hillary Clinton's ties to Russia, a request that was ultimately denied.

"I'm not going to dispute the fact that the full committee has taken a very hands on approach with the subcommittee," a senior House GOP source told The Daily Beast.

Since his attempt to hold a hearing to show the pro-Kremlin propaganda film, The Daily Beast reported Rohrabacher hasn't requested a subcommittee hearing.
