big statement. president biden made a big statement at this conference last year. he said "america is back." so i think there's notice that he's not going this time. we'll watch what happens. >> we'll have the vice president of the united states there. a pretty high level participation. the president has not been a stranger to the munich security conference, nor has any other tom level cabinet officials. >> martha: thanks, john. good to have you with us. >> thanks very much. >> martha: so why a russian figure skater may be at the center of another olympic doping controversy next.
