One newly sworn-in Republican state senator and five GOP Senate candidates have sent a warning shot in the direction of the Texas Ethics Commission, advising the panel to refrain from passing rules that would require politically oriented nonprofit groups to disclose their donors.

In a letter sent over the weekend to Ethics Commission Chairman Jim Clancy, the six Republicans said the commission was overstepping its bounds by attempting action on something that was considered last session by the Legislature. A bill that contemplated doing something similar to what the Ethics Commission is considering now made it to the governor's desk, where it was vetoed.

"We the undersigned strongly discourage the TEC from any attempt to usurp the constitutional authority of the legislative and executive branches by overstepping your authority. Legislating from the TEC bench — seeking to go around the legislative process to enact a law that failed the legislative process — is not something we will support," the group wrote.

The letter writers include state Sen. Charles Perry, R-Lubbock; SD-2 candidate Bob Hall; SD-7 candidate Paul Bettencourt; SD-8 candidate Van Taylor; SD-10 candidate Konni Burton; and SD-16 candidate Donald Huffines.
