Congresswoman Nancy Pelosi said she does not consider Joe Biden's age a "disadvantage" when she was asked about concerns raised by Mitt Romney and political commentators that the age of US leadership is growing increasingly older.
Ms Pelosi appeared on MSNBC, where host Mika Brzezinski asked her to have a "serious conversation" about the age of America's leaders in the wake of Senator Mitt Romney's announcement that he would not seek re-election.
