There are no regulations about tripods on the TSA website.

"You may carry one (1) bag of photographic equipment in addition to one (1) carry-on and one (1) personal item through the screening checkpoint. The additional bag must conform to your air carrier's carry-on restrictions for size and weight. Please confirm your air carrier's restrictions prior to arriving at the airport.

Air carriers may or may not allow the additional carry-on item on their aircraft. Please check with your air carrier prior to arriving at the airport."

It is up to the agents running the security gate. I have carried on my tripod without problem on domestic flights.
