One of the three ethics violations of Tom's was for the trips, I think.
He took checks from corporations. Then, qwithin 60 days of the elections, he passed that money along to the Republican party, with the names of Texas Republicans who he wanted supported. That money was then used in the campaigns. Two problems, within 60 days of the election, and corporate money used to advance the campaign, and not for administartive purposes. This arrose when Delay wanted the Texas districts redrawn, although the timing for the redrawing of the districts was not ready. So, delay got the districts redrawn, then, used the redrawn districts to increase republicans in the House. However, he is now in a fight in his own district, as a result. Poetic justice.
