House Speaker Mike Johnson said Saturday he believes Republicans have the votes to launch a formal impeachment inquiry into President Joe Biden.

“I believe we will,” Johnson told Fox News of a GOP-led impeachment inquiry. “I suspect no Democrats will assist in this effort, but they should.”

Johnson added Republicans “have a duty to do this” and “we cannot stop the process.”

Republican leadership and key GOP committee chairs on Friday made the case for why they believe an inquiry vote is necessary, arguing it would strengthen their legal standing in court and accusing the White House of “stonewalling” their probe into the president and his son’s foreign business dealings – a claim the White House has forcefully rebutted.

Johnson, appearing alongside House GOP conference chair Elise Stefanik, claimed the inquiry wouldn’t be used as a partisan political tool.
