Former FBI Director James Comey urged a judge on Monday to throw out federal charges against him, arguing that an Instagram photo of seashells arranged to read '86 47' was protected political speech, not a true threat against President Donald Trump. Comey's lawyers filed a motion to dismiss the case, saying the government cannot prove the post constituted a call to violence. The charges stem from a post Comey made on social media showing seashells on a beach forming the numbers 86 and 47. Prosecutors allege the post was a threat to kill the president, but Comey's legal team contends it was a form of political expression and does not meet the legal standard of a 'true threat.' The case has drawn attention to free speech boundaries and the ongoing tensions between Trump and Comey, who Trump fired as FBI director in 2017. A judge is expected to rule on the dismissal request in the coming weeks.
