Donald Trump Jr. received an envelope with a death threat and white powder inside.
Tests on the substance were inconclusive, but did not appear to be lethal. This is the latest in a series of threats against political candidates and their families. In December, two men were charged with sending threatening text messages to three GOP presidential candidates, including Donald Trump, who has since dropped out of the race. In 2012, the U.S. House of Representatives passed a bill to make it easier for people to report threats to police.
