Sen. Rand Paul (R-KY) slammed President Trump after he and his family were disinvited from the annual White House picnic.Said Paul: “I think I’m the first senator in the history of the United States to be uninvited to the White House picnic. I just find this incredibly petty. I mean — I have been, I think, nothing but polite to the President.”He added: “The level of immaturity is beyond words.”More: “So, it’s silly in a way, but it’s also just really sad that this is what it’s come to. But petty vindictiveness like this, I don’t know. It makes you wonder about the quality of people you’re dealing with.”
