Story highlights Rogers' testimony Tuesday sparked interest after reports Trump asked him to publicly deny evidence of cooperation

Rogers batted down notion that Obama administration requested that British eavesdrop on Trump

Washington (CNN) Late last year, Adm. Michael Rogers found himself in both the catbird seat and the hot seat all at once.

On one front, he was being considered as a candidate for the job of director of national intelligence under President-elect Donald Trump. On another front, there were questions about whether he would be fired as director of the National Security Agency by then-President Barack Obama.
