text:  This is Weekend Edition from NPR News. I'm Scott Simon. President Biden sat for an interview yesterday with ABC's George Stephanopoulos, and it was widely taken as his chance to regain some confidence from supporters after a faltering debate performance last week against Donald Trump. The president said he isn't dropping out of the race and that he will defeat Trump in November, as he did four years ago. NPR senior White House correspondent Tamara Keith joins us. Tam, thanks for being with us. Glad to be with you.
