California Rep. Dana Rohrabacher says White House aides are preventing President Donald Trump from pardoning WikiLeaks founder Julian Assange.

Rohrabacher made the accusations to The Daily Caller after Trump said he hadn’t heard of any potential deal with Assange. Asked about a possible pardon for Assange on Sunday, Trump replied, “I’ve never heard that mentioned, really, I’ve never heard that mentioned.”

“I think the president’s answer indicates that there is a wall around him that is being created by people who do not want to expose this fraud that there was collusion between our intelligence community and the leaders of the Democratic Party,” Rohrabacher said Tuesday.

Rohrabacher said that Trump could issue a pardon before he has been charged with any crimes.

The congressman said he met with Assange at the Ecuadorian Embassy in London and said Assange denied Russia had any involvement in the hacking of the Democratic National Committee.
