The former Texas congressman sent a text message to KTSM Wednesday afternoon confirming the news that he will seek the Democratic presidential nomination.

He wrote: "I'm really proud of what El Paso did and what El Paso represents. It's a big part of why I'm running. This city is the best example of this country at its best."

O'Rourke was little-known outside his hometown of El Paso until he challenged Republican Sen. Ted Cruz last year. He got within 3 percentage points of upsetting Cruz in the nation's largest red state and shattered national fundraising records while using grassroots organizing and social media savvy to mobilize young voters and minorities.
