OKLAHOMA CITY (AP) - An energy company executive has testified that he knows of no legal work performed by the former leader of the Oklahoma Senate for the company.

Tenaska Inc. vice president Brad Cox testified Wednesday in the trial of former Senate President Pro Tem Mike Morgan - who allegedly received $250,000 from the company. Prosecutors allege that Morgan - who is an attorney - accepted the money as legal services - but performed no legal work.

Cox said payments to Morgan stopped in November 2008 after Morgan left office.

Morgan allegedly conspired with lobbyist William Skeith and attorney N. Martin Springer to illegally accept more than $400,000 from three companies - including Tenaska - in exchange for Morgan's influence on legislation.

All have pleaded not guilty.
