(Portland, OR)  --  A group of military veterans is joining ongoing protests in Portland.  The group showed up to Saturday's protest and formed a protective wall around the demonstrators, standing with their hands clasped behind their backs.  Some of them held signs in support of the Black Lives Matter movement as they stood in front of the federal courthouse.  They joined groups of moms and dads forming a wall of protection from tear gas cannisters and the advance of federal troops.
