Sen. Lindsey Graham, R-S.C., said Friday that President Biden "deserves to be impeached" if the United States leaves any Americans or Afghan allies behind when evacuating Afghanistan. 

"If we leave any Americans behind—if we leave thousands of those Afghans who fought along our side behind bravely—Joe Biden deserves to be impeached for a higher crime and misdemeanor of dereliction of duty," said Graham during an appearance on "Fox & Friends."

Graham again clarified his statement with more precision. 

"If we leave one American behind. If we don’t get all those Afghans who stepped up to the plate to help us out then Joe Biden, in my view, has committed a high crime and misdemeanor under the Constitution and should be impeached."

Graham asserted that the U.S. is "duty-bound" to get every American out of Afghanistan safely, and also "honor-bound" to do the same for Afghans who fought alongside American soldiers.
