Oregon Second District Congressman Greg Walden says he was honored to help escort Israeli Prime Minister Benjamin Netanyahu into the chambers to make his address to Congress Tuesday, and shares his concerns about negotiations with Iran.  The Hood River Republican says a nuclear Iran poses a threat to America, Israel, and the world.  Netanyahu claimed in the speech the negotiation between the U.S. and Iran will “all but guarantee” Iran will develop nuclear weapons.  But President Barack Obama says Netanyahu made almost the same speech when he warned against the interim deal with Iran that Obama says resulted in a freeze and rolling back of Iran’s nuclear program.
