President Obama talked briefly about Venezuela in an interview, giving a statement that's pretty bland:
Set aside for now the fact that Venezuelan elections have been free and fair, but that the opposition mostly loses. Obama's idea is that you pay attention but don't over-react. This made Marco Rubio mad, because he's firmly in the over-react camp.
It's never quite clear, though, what Rubio and others actually want. I am guessing sanctions, but if the national security of the United States is the goal, then we'd be shooting ourselves in the foot because oil prices would likely jump and Chávez would receive considerable sympathy. Or maybe just more money for the Venezuelan opposition, though that's not a terribly effective tool. Or covert ops, I suppose. But even if you support those, you have to know that the probability of discovery is very high, and that would create backlash.
