Trump's former advisor Stone notify court he abused gag order

President Donald Trump's former political adviser Roger Stone told a court on Thursday that he had abused a gag order imposed following criminal charges against him in the Russian election interference probe with an Instagram post showing the judge next to an image that appeared to show the crosshairs of a gun.

"I abused the order," Stone told U.S. District Judge Amy Berman Jackson during a hearing to examine whether he should be sanctioned. "I am kicking myself over my own stupidity."
