The U.S.-Mexico border remains susceptible to terrorist infiltration and needs more investment for homeland security, a Texas congressman says.

U.S. Rep. Jim Turner said he and Rep. Silvestre Reyes want to create a $1 billion infrastructure investment fund aimed at closing the security gaps and bolstering the economy along the 2,000-mile border...

"We cannot pretend that our homeland is secure if our borders are not," said Turner. "We firmly believe that America is at risk if we do not immediately take action to close these security gaps."

Doubling law enforcement personnel along the border, deploying technology for constant monitoring, screening cargo trucks for weapons and expanding detention operations for illegal immigrants are among Turner's proposals.

Last year, 24,000 undocumented immigrants from countries other than Mexico were apprehended by the Border Patrol, but released on bond in the United States because of lack of detention space," Turner said.

"Although we're hearing a lot about taking the fight to the terrorists in the war on terror," said Reyes, "we also know that in practical terms, we have got to do a better job of defending the homeland."
