The grand jury has been investigating whether $2.5 million in corporate funds were used illegally to help Republican candidates win elections in 2002 that gave the GOP a majority in the Texas House for the first time since Reconstruction. The GOP later used its majority to redraw Texas' congressional districts to favor Republican candidates.
The Austin American-Statesman reports that those charged include John Colyandro, the executive director of DeLay's PAC, Texans for a Republican Majority; James Ellis, a key aide to DeLay; and Warren Robold, aWashington, D.C., fund-raiser.
Ellis was charged with money laundering. Colyandro and RoBold were charged with unlawful acceptance of corporate political contributions. The eight companies were charged with making illegal political contributions.
DeLay was not questioned or subpoenaed as part of the grand jury investigation.
Calls to the defendants or their lawyers were not immediately returned.
