Maryland Gov. Martin O’Malley plans to return to Iowa this weekend, just a month after he was the keynote speaker at the state’s Democratic party convention.

O’Malley (D), who is preparing for a possible 2016 White House bid, had previously announced travel this weekend to neighboring Nebraska, where is scheduled to address the annual Morrison Exon Dinner in Omaha on Saturday night.

During his time in Iowa, O’Malley will attend four fundraisers, including two for state Senate candidates earlier Saturday and two on Sunday for Jack Hatch, the Democratic nominee for governor, an aide said.

O’Malley has said he is giving serious consideration to a presidential bid and will not wait for Hillary Rodham Clinton to decide whether she is running.

He has had the most active travel schedule of other potential Democratic candidates, appearing at numerous party dinners and fundraisers for other Democrats across the country.

This past weekend, O’Malley hosted a fundraiser in Easton to benefit five congressional candidates. It was attended by House Minority Leader Nancy Pelosi (D-Calif.).

The fundraisers this weekend in Iowa, the nation's first presidential nominating state, will take O’Malley to Clinton, North Liberty, Council Bluffs and Sioux City.
