"So about all that lying: Reporters were curious why anyone should believe her or Trump for that matter, who totally lied aboard Air Force One in March when he said he knew nothing about the payment. "When the president, or the White House, shows what appears to be a blatant disregard for the truth, how are the American people to trust or believe what is said here or what is said by the president?" asked Jon Karl. Sanders again said: "We give the very best information that we have at the time." Apparently the "best information" is lot like Trump’s "best people," many of whom have turned out to be corrupt, power-hungry, incompetent, thieves. Of course, the president didn't give the best information on Air Force One. He lied. And when Sanders was asked directly about the lie Trump peddled on Air Force One that he didn't know about payments, Sanders appeared to lie again."
