Just over 10 weeks after the idea was first proposed in a Facebook post, tens of thousands of protesters are heading to the nation's capital for the Women's March on Washington on Saturday.

Similar marches are planned in more than 600 other cities and towns around the world. But the largest is expected to take place in Washington, D.C., less than 24 hours into the presidency of Donald Trump.

The looming presidential inauguration of Donald Trump has sparked rallies and demonstrations around the country. In Ohio progressive groups are jumpstarting their activism to save government programs such as Obamacare and Social Security.

An estimated two thousand people marched through downtown Columbus in a preview of the Women’s March on Washington this weekend after President-Elect Donald Trump’s inauguration.

The day after President-elect Donald Trump's inauguration, Jan. 20, 2017, a march is slated to take place on the National Mall.

The governor of North Dakota says he has not authorized roadblocks or forcible removal of protesters from the area near the route of the Dakota Access Pipeline.

Gov. Jack Dalrymple spoke to reporters in an effort to clarify the implications of an evacuation order he issued earlier this week, which he said had led to "some miscommunication" with local law enforcement.

The U.S. Army Corps of Engineers notified the Standing Rock Sioux Tribe on Friday that the public will not be allowed in areas being used to protest the Dakota Access Pipeline.

In a letter to the tribe, John W. Henderson, a district commander with the Corps, said that the area will be closed by Dec. 5. Anyone found to be on "Corps-managed land" north of the Cannonball River after that date will be considered trespassing and subject to prosecution:

Issue 3 Protest

Nov 6, 2006

40 horse trailers Sunday formed a ring around a downtown block of Dayton. It was a protest against the Dayton Daily News by families who work in the horse-racing industry. They were upset that the newspaper has written strong editorials against State Issue 3 the ballot issue that would allow Ohio race tracks to install electronic slot machines. The demonstration revived debate over whether the state should help out a floundering industry. Statehouse correspondent Bill Cohen files this report.
