A 17-year-old from Illinois who is charged with killing two people during a protest in Wisconsin and whose case has become a rallying cry for some conservatives has posted $US2 million ($A2.7 million) bail and has been released from custody.
Kyle Rittenhouse is accused of fatally shooting Joseph Rosenbaum and Anthony Huber and wounding Gaige Grosskreutz during a demonstration on August 25 that followed the police shooting of Jacob Blake in Kenosha.
Rittenhouse, of Antioch, Illinois, told police he was attacked while he was guarding a business and that he fired in self-defence.
He faces multiple charges, including intentional homicide, reckless endangerment and being a minor in possession of a firearm.
Wisconsin law doesn't permit minors to carry or possess a gun unless they're hunting. He is due back in court on December 3 for a preliminary hearing.
His case has taken on political overtones. Supporters of the Black Lives Matter movement have painted Rittenhouse as a trigger-happy white supremacist.
Conservatives upset over property destruction during recent protests have portrayed him as a patriot exercising his right to bear arms during unrest.
A legal defence fund for him has attracted millions of dollars in donations, and his mother got a standing ovation from women at a Waukesha County GOP function in September.
The man charged with buying the rifle that police say Rittenhouse used will stand trial, a court commissioner decided on Thursday.
Dominick Black, 19, was is charged in Kenosha County Circuit Court with two counts of intentionally providing a dangerous weapon to a minor, resulting in death.
