President Obama should stay involved in politics after he leaves office even if that means overstepping the usual role of an ex-president, a top House Democrat said Tuesday.

Rep. Elijah Cummings, D-MD, said on CNN Obama needs to act as a bulwark against Trump and Republican lawmakers when he leaves office. Ex-presidents typically keep a low profile when they leave the White House in a show of deference to the new chief executive, but Cummings said the times are such that Obama could change that.
