(AP) -- Hillary Clinton is turning to the symbolism of Abraham Lincoln's "House Divided" speech to argue that the nation needs to repair its divisions after high-profile shootings in Texas, Louisiana and Minnesota.

Clinton's campaign says the Democratic presidential candidate will talk about the importance of uniting the country at the Old State House in Springfield, Illinois, later Wednesday. It's the site of Lincoln's famous address in 1858.

Clinton plans to say the nation needs to determine ways to close the divides exposed in the recent shootings.

But she will say that the problems facing the country are much broader and show the need to heal divisions in the nation's politics and culture.

Heading into the Democratic convention, Clinton has tried to present herself as a unifying figure against Republican Donald Trump.
