Roger Stone, a longtime political adviser to President Donald Trump who was arrested Friday on accusations of lying to Congress, said he would consider cooperating with special counsel Robert Mueller in his probe of Trump campaign ties to Russian election interference in 2016.

In an ABC News interview Sunday, host George Stephanopoulos asked Stone whether there was any chance he would cooperate at Mueller’s request.

“You know, that’s a question I would have to — I would have to determine after my attorneys have some discussion,” Stone said. “If there’s wrongdoing by other people in the campaign that I know about, which I know of none, but if there is, I would certainly testify honestly.”

Stone added: “I’d also testify honestly about any other matter, including any communications with the president. It’s true that we spoke on the phone, but those communications are political in nature, they’re benign, and there is, there is certainly no conspiracy with Russia.”
