POLITICO's Juana Summers reports:


Herman Cain canceled a scheduled appearance at his Iowa campaign headquarters after Occupy Wall Street protesters arrived at the Urbandale office.

Cain, according to Iowa campaign chair Steve Grubbs, was scheduled to appear at the office at 2:45 p.m. and meet with supporters, as well as speak to reporters.

However, upon arriving at the Iowa office both reporters and Cain fans were told that the Atlanta businessman would not be in attendance.

The Iowa staffer told POLITICO that the campaign had chosen to cancel Cain's trip there because they did not want media reports of protesters and police.

Cain instead took questions from reporters outside the Machine Shed, an Urbandale restaurant where he was filming a video.
