Paul Ryan said on "Fox News Sunday" that the House of Representatives will not interfere with Special Counsel Robert Mueller's investigation into Russian interference in the 2016 election and allegations of collusion with the Donald Trump campaign.
"Will you pledge that you will not allow the Mueller investigation to be curbed or stopped?" host Chris Wallace asked.
"I've said all along we need to let these career professionals do their job, see it through. So no, I don't think he should be stepping down, I don't think he should be fired," Ryan said.
"It will take its course and we will let it take its course," Ryan said.
He mentioned that Congress is doing its own investigations into Russia.
"We need to figure out exactly what they did to our country, how and why they did it, and then how do we prevent them from doing it in the future," he said.
Republican Reps. Matt Gaetz (R., Fla.), Andy Biggs (R., Ariz.) and Louie Gohmert (R., Texas) introduced a measure on Friday seeking Mueller's resignation from the probe for what they call conflicts of interest.
