Sunday on ABC’s “This Week,” chief White House correspondent Jonathan Karl said the indictment of Sen. Bob Menendez (D-NJ), who is a strong supporter of Israel and opposes President Barack Obama going ahead with an Iran nuclear deal without congressional approval, will make it harder for Republicans to persuade other Democrats to go against the president and override a veto on Sen. Bob Corker (R-TN) legislation calling for congressional oversight.

Martha Raddatz asked, “Sen. Robert Menendez who was indicted on corruption charges. He pleaded not guilty to counts of bribery, corruption, fraud. He’s temporarily stepping down as the ranking member of the foreign relations committee, right as Iran is coming up. He was the principal critic on Iran. Will it make a difference?”

Karl said, “If you had written this in a ‘House of Cards’ script, it would have been thrown out. The idea that the president’s most powerful democratic critic of the Iran deal goes down, indicted just before the deal is announced, nobody is suggesting a connection, but it sure does have an impact and it will it will be harder for Republicans to get a veto-proof majority to challenge the deal.”
