security disaster in our history. i think it will be a top priority. and senator lindsey graham, the man who refused twice to vote to convict donald trump, is now threatening to impeach joe biden over afghanistan. >> if we leave any americans behind, 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 dare election of duty. if we leave one american behind, if we don't get the afghans who stepped up to the plate to help us out, then joe biden, in my view, has kmiet committed a high crime and misdemeanor under the constitution and should be impeached. >> david, a white house senior advisor for president obama. thanks for coming on the show. you experienced republican bad faith attacks benghazi.
