Hillary Clinton wants voters to consider what Republican front-runner Donald Trump might do to shape the Supreme Court.

Clinton planned to use in a speech in Madison, Wisconsin, on Monday to argue that Trump could roll back the rights of individuals, further empower corporations and undo some of the nation's progress.

Clinton was campaigning in Wisconsin ahead of the state's April 5 primary and speaking Monday at the University of Wisconsin about President Barack Obama's nomination of Judge Merrick Garland.

Clinton holds a large lead among delegates against Democratic rival Bernie Sanders but is trying to stamp out the Vermont senator's momentum following his victories in five of the last six states holding contests.

Clinton's campaign said ahead of the speech that the Democratic presidential candidate would call on Senate Judiciary Chairman Charles Grassley of Iowa to commit to giving Garland a hearing. Grassley and Senate Majority Leader Mitch McConnell, R-Ky., have said that the late Justice Antonin Scalia should not be replaced until the next president picks a nominee.
