WASHINGTON (Reuters) - U.S. President Donald Trump's former adviser Roger Stone lost a last-ditch effort on Tuesday to lift a court-imposed gag order barring him from posting on social media or discussing his criminal case slated to begin next month.

In a unanimous ruling, the U.S. Court of Appeals for the District of Columbia Circuit refused to overturn the gag order imposed by a lower court, saying Stone and his family had "failed to avail themselves of adequate alternative remedies" to address their concerns that the gag order violated Stone's First Amendment free speech.
