DeLay admitted to DA Earle that he was aware of the money movement before it happened

The Washington Post states that the proof DA Ronnie Earle has that Tom DeLay knew of and approved of the transfer of funds from corporations throught the Republican National Committee to Republican candidates for the Texas House of Representatives.

That means that DeLay knew and approved in advance of the shift of money from corporations to Texas candidates, going through the RNC to conceal that the money was from corporations. The use of corporate money to fund election activities is illegal under Texas Law, which is why the money could not be sent directly from the corporations to the candidates.

This is the classic definition of money laundering. Money from an illegal source is transferred throught intermediate organizations to conceal the illegal source.

DeLay dug his own grave.
