Video! Alec Baldwin Occupies Wall Street with Protestors

Burgeoning politico Alec Baldwin showed up at an "Occupy Wall Street" protest Tuesday.

The "30 Rock" star advocated for tighter bank regulations. Arriving around midnight, he tweeted at 1:37, "My thanks 2 Aaron from Brooklyn and Sean from Winnipeg for this evening's OWS tutorial. My first. A lot of dedicated people at #ZuccottiPark."

Baldwin was also greeted by detractors who cited his work as a spokesperson for Capital One Bank.

He tweeted on the issue, as well. "I donated all of my fee from Capital One 2 arts charities. They have been gr8 partners in my support of the arts." The star then followed that defense of banks' existence, saying, "We need a healthy banking system in this country. We need strong capital markets. What is missing are regulations with teeth."
