Confusion over masks sparks new political showdown

America's emerging limbo between a full-blown pandemic and a return to normal is throwing up new public health dilemmas that spark instant political fires -- like a fresh round of grandstanding over mask wearing.

Top White House adviser Anita Dunn Sunday defended President Joe Biden over his continued use of a mask outdoors -- even though the practice appears to conflict with new and relaxed administration guidelines for fully vaccinated citizens. In comments that didn't necessarily clarify the situation, Dunn told CNN's Jake Tapper on "State of the Union" that "extra precautions" were being taken for the President and that mask wearing was "a matter of habit."
