Washington Gov. Jay Inslee Jay Robert InsleeBarr asked prosecutors to explore charging Seattle mayor over protest zone: report Bottom line Oregon senator says Trump's blame on 'forest management' for wildfires is 'just a big and devastating lie' MORE's (D) presidential campaign released a 10-step plan to combat white nationalist gun violence Tuesday in the aftermath of last weekend's back-to-back mass shootings that killed more than 30 people.

The strategy, which builds on Inslee's work on the issue as governor, begins with directing federal law enforcement agencies, including the FBI, Department of Homeland Security and State Department, to establish systems to track and prosecute extremists.

The plan also involves expanding international cooperation to combat white nationalist extremism.

The governor's campaign did not specify how much the plan would cost.

Inslee would also institute bans on assault weapons and untraceable firearms, in addition to closing the "Charleston loophole," referring to the gap in the background check system which allowed a man to purchase a firearm and kill nine people at South Carolina's Mother Emanuel Church in 2015.

The plan comes as Inslee's fellow 2020 Democratic presidential candidates, as well as Democratic lawmakers, call for stricter gun control measures after the mass shootings last weekend in El Paso, Texas, and Dayton, Ohio.

The suspected gunman in the El Paso shooting allegedly wrote a racist, anti-immigrant manifesto before the attack, which described fears of a Latino “invasion."
