Donald Trump vows to track illegal immigrants on visas

In a campaign speech in Des Moines, Iowa, Trump also cited the shooting death of a cousin of NBA star Dwyane Wade to urge African-American voters to rally behind him, calling it an example of violence that has to be addressed.
Trump said he would seek to institute a tracking system to ensure illegal immigrants who overstay their visas are quickly removed, and would propose an e-verify system to prevent the illegal community from gaining access to welfare and other benefits.
