Rep. Larry Bucshon, R-Ind., told Newsmax on Monday that "it's pretty clear to see" that President Joe Biden is struggling with a decline in cognition.
"The American people are seeing it," Bucshon, who is also a medical doctor, said on Newsmax's "National Report." "You don't have to have a special counsel report to recognize that the president has some level of mental impairment.
"I've recently been through this with my mother. I think it's honestly a sad situation. I think people around the president, particularly his family, need to recognize this.
"Honestly, he needs to drop out of the presidential race. I think that the president clearly has some level of impairment, and I'm worried about that from a national security standpoint, but more, I'm worried about the president himself and his family. This is really something that they should be telling him, to drop out of this race."
The Justice Department on Thursday released special counsel Robert Hur's report on the investigation of Biden's mishandling of classified documents after his vice presidency. The special counsel did not recommend charges for the president because he was likely to present himself to a jury as a "well-meaning, elderly man with a poor memory."
Several Republican lawmakers have called on Biden, 81, to step down. Rep. Claudia Tenney, R-N.Y., sent a letter to Attorney General Merrick Garland and other members of the Biden administration last week, asking them to explore invoking the 25th Amendment to remove the president from office.
In an interview before the release of the special counsel's report, Vice President Kamala Harris said she's ready to lead if necessary amid renewed concerns about Biden's age.
"I am ready to serve," Harris told The Wall Street Journal on Tuesday.
