Rick Santorum favors curbs on legal immigration

AMES, Iowa — At the annual Family Leadership Summit here today, several Republicans presidential candidates vowed to stop illegal immigration.

But Rick Santorum says the U.S. needs to curtail legal immigration as well.

The former Pennsylvania senator says the vast majority of immigrants coming into the U.S. – legally and illegally – are driving down wages for American-born workers.

Santorum told Iowa evangelical voters that "we need to hold the line and stop illegal immigration" while reducing legal immigration of unskilled workers by 25 percent. He says that will help bring up wages in the U.S.

Santorum is among 10 presidential candidates courting religious conservatives in Iowa. He won the state's caucuses in 2012, but faces strong competition for the evangelical vote in 2016.
