On Capitol Hill, a Democratic congressman from Texas plans to file a wide-ranging ethics complaint today against House Majority Leader Tom DeLay accusing him of soliciting campaign contributions in return for legislative favors; laundering illegal campaign contributions through a Texas political action committee; and improperly involving a federal agency in a Texas partisan matter. The complaint by Rep. Chris Bell is unusual in that it breaks a seven-year-old unwritten truce between the two parties against filing ethics complaints against each other.
