COLUMBUS, Ohio--Hillary Clinton's campaign announced Tuesday it plans to open its first three satellite field offices in Ohio this week, in Cleveland, Toledo, and Cincinnati.

The offices, which come weeks after the presumptive Democratic presidential nominee opened her state headquarters in Columbus, mark the latest ramp-up by the Clinton campaign to win Ohio, a key swing state.

In recent elections, presidential campaigns from both parties have began setting up Ohio field offices around this time as well. Unusually, though, Clinton's presumed GOP rival, Donald Trump, has yet to open any campaign offices in the Buckeye State.
