Donald Trump's federal cops used batons and tear gas to fight off Portland's moms last night as protests entered day 55 in the city amid a growing backlash against the president's troops. 

Armed with assault rifles, federal cops pushed back against the helmet-wearing 'Wall of Moms' who were protesting their presence in the city and acting as human shields for Black Lives Matter protesters. 

Footage showed the cops dispersing protesters with their bare hands and shoving some of the women in the chest while using tear gas to break up the crowds on Tuesday night. 

The group of mothers and fathers have been forming a human barrier between demonstrators and police at protests this week, amid allegations of brutality by the federal agents. 

As well as the backlash in the streets, the Trump administration is also facing one in the courts, with several lawsuits filed in the last week in efforts to force the federal agents out of the city.  

This comes as Trump continues to plow ahead with his law and order takeover in Democrat-run states, as he vowed to send in 150 agents to tackle the wave of violence and ongoing protests in Chicago. 

Hundreds of protesters gathered in the streets of Portland Tuesday night, holding banners aloft as they marched peacefully through the city. 

The 'Wall of Moms' led protests outside the Multnomah County Justice Center, sporting their signature yellow t-shirts.
