The SEIU held a large rally in downtown Los Angeles Monday in support of Huerta and to stand up for his right to observe and document law enforcement activity. Union leaders from across the state led the crowd in chants of “Free Huerta now!”Demonstrations were also planned in at least a dozen cities, from Boston to Denver.

The union has been a strong Democratic supporter, and Senate Democratic Leader Chuck Schumer and California’s two Democratic senators wrote a letter to federal officials demanding answers regarding Huerta’s arrest. California Sen. Adam Schiff was at the court ahead of Huerta’s hearing.“It is deeply troubling that a U.S. citizen, union leader, and upstanding member of the Los Angeles community continues to be detained by the federal government for exercising his rights to observe immigration enforcement,” the senators wrote.broke out last week in response to reports of immigration raids in the nation’s second-largest city. Tensions have since escalated with thousands of protesters taking to the streets after Trump

the National Guard. Demonstrators blocked a major freeway and set self-driving cars on fire as law enforcement usedand rubber bullets to control the crowd.

Huerta was arrested Friday when law enforcement officers were executing a federal search warrant at a Los Angeles business suspected of hiring illegal immigrants and falsifying employment papers, a special agent for Homeland Security Investigations, which is part of Immigration and Customs Enforcement, wrote in a court filing.

A crowd of people including Huerta gathered outside the business yelling at the officers. Huerta sat down in front of a vehicular gate and encouraged others to walk in circles to try to prevent law enforcement from going in or out, the agent wrote, adding it was clear “he and the others had planned in advance of arrival to disrupt the operation.”. And the IAEA’s work in any case will make the Vienna-based agency a key player.

Here’s more to know about the IAEA, its inspections of Iran and the deals — and dangers — at play.The IAEA was created in 1957. The idea for it grew out of a 1953 speech given by U.S. President Dwight D. Eisenhower at the U.N., in which he urged the creation of an agency to monitor the world’s nuclear stockpiles to ensure that “the miraculous inventiveness of man shall not be dedicated to his death, but consecrated to his life.”

Broadly speaking, the agency verifies the reported stockpiles of member nations. Those nations are divided into three categories.The vast majority are nations with so-called “comprehensive safeguards agreements” with the IAEA, states without nuclear weapons that allow IAE monitoring over all nuclear material and activities. Then there’s the “voluntary offer agreements” with the world’s original nuclear weapons states — China, France, Russia, the United Kingdom and the U.S. — typically for civilian sites.
