McALLEN - The Texas Democratic Party has received reports of unknown persons calling and e-mailing delegates to incorrectly inform them their county and senate district conventions have been cancelled, said party spokesman Hector Nieto.

Nieto said several delegates had reported incidents to party officials, but he did not know where in Texas they hailed from. He said party officials were investigating who's behind the misinformation campaign.

Party officials have also received reports of delegates receiving "robo-calls," also claiming conventions have been cancelled.

Texas Democratic Chairman Boyd Richie urged delegates to attend their conventions unless contacted by their local Democratic county chair or a postponement is posted on the Texas Democratic Party's website, www.txdemocrats.org.

"The Texas Democratic Party has not been informed that any county or district convention has been cancelled or postponed.  If any delegates receive information to that effect, I urge them to plan to attend their convention as scheduled," Richie said.
