An elderly U.S. Army veteran will go on trial next month for hanging two American flags at a Veterans Affairs facility.

Robert Rosebrock, 74, faces a criminal charge for displaying an American flag without permission outside the Greater Los Angeles Veterans Affairs facility.

He also faces a charge for taking unauthorized photos of VA officers.

Robert Rosebrock, 74, faces a criminal charge for displaying an American flag without permission outside the Greater Los Angeles Veterans Affairs facility. He placed the flags on a fence during a protest last May of Veterans Affairs's treatment of homeless veterans.

Rosebrock served in the Army from 1965 to 1967 and has protested VA treatment of homeless vets every Sunday since March 2008. He and other veterans began to attract some controversy after hanging flag upside-down in 2009, but they stopped doing so in 2010

If convicted, Rosebrock could serve up to six months in prison, Fox News reported.

Rosebrock, who has pleaded not guilty, placed the flags on a fence during a protest last May of Veterans Affairs's treatment of homeless veterans.

A 1973 VA edict states that individuals may only place materials on VA property with permission.

The charges were filed under the Obama Administration and Rosebrock's legal counsel hopes the Trump administration, and in particular attorney general Jeff Sessions, will see his actions differently

He and other veterans began to attract some controversy when they started hanging the flag upside-down in 2009, but stopped doing so in 2010, a representative for Rosebrock said.

The charges were filed under the Obama Administration and Rosebrock's legal counsel hopes the Trump administration, and in particular attorney general Jeff Sessions, will see his actions differently.

Judicial Watch President Tom Fitton told Fox: 'Frankly, President Trump should ask why the VA and his Justice Department are trying to jail this American patriot.'
