Fresh off a victory in Washington state, a leading gun control group, Everytown for Gun Safety, has targeted Oregon as the next prize in a campaign to require all gun sales go through background checks to keep them from criminals, the mentally ill and domestic abusers.

GRANTS PASS, Ore. — Fresh off a victory in Washington state, a leading gun control group backed by billionaire Michael Bloomberg hopes to make Oregon its next prize in a campaign to require all gun sales go through universal background checks.

Everytown for Gun Safety spokeswoman Erika Soto Lamb says background checks are their top priority, and they hope to pick up a win in Oregon.

Everytown backed a voter-approved initiative in Washington last year that made it the 17th state to expand background checks beyond the federal standard, which applies only to licensed gun dealers.

Now Everytown's attention is on Oregon, where the state Legislature will consider a bill to require checks on private gun sales. With help from Everytown last fall, Democrats expanded their majority to 18-12 in the Senate.
