FILE - In this Sunday, Sept. 4, 2011 file photograph, President Barack Obama walks with Sen. Robert Menendez, D-N.J., in Newark, N.J., as they returned from Paterson, N.J., after viewing damage caused by Hurricane Irene. In January 2013, the senator’s role in Washington grew as he became chairman of the Foreign Relations Committee and was a major player in a bipartisan Senate plan to overhaul the nation’s immigration laws. At the same time, he has been in the familiar situation of fending off charges of impropriety. He’s repaid a donor for travel in a private jet and tried to shoot down stories that he’s patronized prostitutes in the Dominican Republic.(AP Photo/Charles Dharapak, File)
