Hillary Clinton said Monday that the future of the Supreme Court would hang in the balance of the 2016 election, warning that Republican front-runner Donald Trump would bring division to the court if he was allowed to shape its future.

Clinton said Trump would roll back the rights of individuals and further empower corporations, pointing to his past statements about building a wall along the Mexican border and barring all non-citizen Muslims from entering the United States.

"In a single term, the Supreme Court could demolish pillars of the progressive movement," Clinton said at the University of Wisconsin. She pointed to the possibility of a Trump presidency, asking, "What kind of justice will a President Trump appoint?"

Clinton opened a two-day campaign trip in Wisconsin ahead of the state's April 5 primary with a topic certain to unite Democrats whether they support her or Vermont Sen. Bernie Sanders: President Barack Obama's nomination of Judge Merrick Garland.

Republicans have said the late Justice Antonin Scalia should not be replaced until the next president picks a nominee. But Clinton argued it was reminiscent of GOP-led gridlock that stymied Obama's two terms.

"We chose a president. We chose him twice," Clinton said. "And now Republicans in the Senate are acting like our votes didn't count and President Obama is not still our nation's leader."
