DeLay maintained public silence on Houston's 2003 METRORail light rail initiative, though in the past, he had opposed expanding light rail to Houston. Public filings later showed that DeLay had his Americans for a Republican Majority Political Action Committee (ARMPAC) and his congressional campaign committee sent money to Texans for True Mobility, an organization that advocated against the initiative. The proposal passed by a slim margin. Despite his earlier opposition, following the passage of the initiative, DeLay helped to obtain funding for the light rail program.
