It seems all four big name Senate candidates plan to release their tax returns ahead of the primary election.

Lt. Gov. David Dewhurst and pledged Thursday to release his earnings statement.

Dewhurst’s campaign tells Capital Tonight that the full returns for 2009 and 2010 will be released tomorrow afternoon. The lieutenant governor will also release a detailed estimate for his 2011 earnings.

Leppert’s campaign said the former mayor would "absolutely be releasing his tax returns in the coming days" and that he "firmly believes that members of Congress should face stronger disclosure requirements."

In a statement, the campaign said :

"We should also increase the transparency of the legislative system by strengthening the disclosure requirements for congressional members, staff and candidates. The current financial disclosure is meaningless. We must have real disclosure."

Former Solicitor General Ted Cruz told Capital Tonight earlier in the day that he would release his returns, if everyone else did. Former ESPN analyst Craig James released his earnings statement during a news conference in Dallas, this afternoon.
