WASHINGTON - The White House announced Friday that President Trump signed an Executive Grant of Clemency commuting the "unjust sentence" of Roger Stone, just days before the longtime political operative is slated to report to prison to serve more than three years for charges stemming from former Special Counsel Robert Mueller’s investigation.Earlier Friday, an appeals court denied Stone's request to delay reporting for his sentence, saying he must report for prison on Tuesday."In sum, Stone is not legally eligible for further postponement of his reporting date under 18 U.S.C. § 3145(c), which is the only basis on which he seeks relief from this court.
