UPDATE 1-Leader of armed group stopping migrants at U.S. border boasted of assassinations-FBI

The leader of an armed group that is stopping undocumented migrants who cross into the United States from Mexico had boasted about training to assassinate former President Barack Obama and Hillary Clinton, an FBI agent said in court papers on Monday.

Larry Hopkins, leader of the United Constitutional Patriots group, whose camouflage-wearing armed members claim to have helped U.S. officials detain some 5,600 migrants in New Mexico desert in the last 60 days was arrested Friday on a weapons charge. The FBI in court papers filed on Monday said that while investigating Hopkins' group in 2017 witnesses had accused Hopkins of saying the UCP was planning to assassinate Obama, former Democratic presidential candidate Clinton and financier George Soros.
