In past personal financial statements, Watson has not disclosed that he shares a business interest with a lobbyist, Curtis Fuelberg, in Frontier Bank. Watson told the Tribune that, under his interpretation of state disclosure rules, he was not required to report it.

Watson has been leading a campaign to build a medical school in Austin along with Central Health, which has paid Brown McCarroll more than $260,000 since May for legal work on the plan, according to the Austin American-Statesman. Watson has rejected the idea that the relationship could present a conflict, and ethics experts contacted by the newspaper found no wrongdoing.

He has received vacation-related gifts from Ben Barnes, the former Texas House speaker and lieutenant governor turned lobbyist, and Steve Hicks, a University of Texas regent, according to filings.
