EDINBURG - District 40 Rep. Aaron Peña, D-Edinburg, officially kicked off his re-election campaign last week.

The announcement came during a kickoff party held Thursday at the Echo Hotel in Edinburg, according to a campaign release.

"I am truly humbled by the outpouring of support from family friends and my community," Peña said in a statement. "...I look forward to continue serving this district with honor and energy."
