Clinton will say Tuesday “that we cannot settle for proposals that provide hard-working people with merely a second-class status,” the aide said, noting a subtle knock against Republican hopefuls — like former Florida Gov. Jeb Bush and Florida Sen. Marco Rubio — who have backed legalization efforts but not full citizenship.

The appearance will be Clinton’s opening salvo on immigration, not her detailed policy rollout, the aide added. That won’t come until late summer or early fall.

Immigration has been a highly motivating issue for Latino voters in the past and Clinton’s campaign will look to keep that up by highlighting where Clinton differs with Republicans on the issue.

“Whoever the Republican nominee is, they will have to go through the primary,” said one Clinton aide. “And at best, they will have to support second class status for immigrants in order to get through that primary, which is a position that will be untenable in a general election.”
