(Univision) MILWAUKEE, Wis. -– Mitt Romney on Monday flatly accused President Obama of reneging on his campaign promise to bring up sweeping immigration reform, despite enjoying a Democrat-controlled Congress for his first two years in office.

“This has always been a priority for the President he chooses to do nothing about,” Romney said. “Let the immigrant community not forget that, while he uses this as a political weapon, he has not taken responsibility for fixing the problems we have.”

The former Massachusetts governor’s decision to turn his sights to Obama on the immigration issue comes as he’s inching closer to securing the Republican presidential nomination.
