Her being accompanied by Kucinich doesn't give her actions any more legitimacy. They both didn't tell anyone else in Congress about the trip and only got the minimum amount of permission needed to travel safely. And secretly traveling to a country torn apart by civil war and human rights violations is completely different than McConnell inviting Netanyahu to address Congress; there's no way to analogize those two actions. (And - at least all of Congress got to hear what Netanyahu was saying and knew he was coming!) NOT the same thing at all as a risky flight to meet peacefully with the leader of a country who is unanimously condemned by the leaders of the free world as committing serious war crimes and human rights violations in the very country where such crimes are being committed.
