Roger Stone spoke to a rightwing gathering called the Mother of All Rallies on Saturday.
The event, which happened on the National Mall as torrential rains pounded Washington D.C., attracted a wide swath of extremists.
That included Stone, who rattled off advice to the president.
“What the president needs to do today is very clear,” Stone said. “He should fire Jeff Sessions, send the Keebler elf, send the insubordinate hillbilly, back to Alabama.”
Stone also said that Trump is facing a do-or-die situation on the Mueller probe and has no choice but to keep pushing forward. Stone said Trump’s only option is to fire special prosecutor Robert Mueller and face the wrath.
“And then, he should fire Mr. Mueller,” Stone said. “To those who say if he does this he will be impeached—if he doesn’t do this he will be impeached.”
