Sen. Markwayne Mullin (R-OK) attacked Hunter Biden when asked about billionaire Elon Musk's outsized role in influencing President-elect Donald Trump and the Republican Party. During an interview on Fox News Sunday, Mullin touted Musk as the solution to government spending after the billionaire temporarily derailed a bill to prevent a government shutdown. "We're going to bring in Elon Musk and allow him to help us see what we aren't being able to see," Mullin told host Shannon Bream, referring to the unofficial Department of Government Efficiency (DOGE).
