Rand Paul actually said...

"They’re afraid of what I’m saying, so they think they’re going to punish me, I can’t go to the picnic, as if somehow that’s going to make me more conciliatory."

"I think I’m the first senator in the history of United States to be uninvited to the White House picnic."

"I’m arguing from a true belief and worry that our country is mired in debt and getting worse, and they choose to react by uninviting my grandson to the picnic."

"I just find this incredibly petty."
