WASHINGTON (Reuters) - President Barack Obama said on Friday his top legislative affairs aide, Katie Beirne Fallon, is leaving the White House and will be replaced by her deputy, Amy Rosenbaum, a former aide to House Democratic Leader Nancy Pelosi. Obama, in a statement, credited Fallon with helping the White House “build up our relationships with folks in both parties” in Congress on issues like the budget, the Iran nuclear deal, and reauthorizing the Ex-Im Bank.
