Roger Stone, a political consultant and longtime confidant of President Donald Trump , has dropped his appeal of felony convictions for lying to Congress and witness tampering, a month after Trump commuted his prison sentence .

My attorneys have convinced me that the odds of victory were slim and the risk of being subjected to both an unfair appeal and perhaps an unfair second trial before the same Judge was just too great a risk, Stone said in a statement posted Tuesday on his website.

His lawyers filed a notice withdrawing the appeal with the U.S. Court of Appeals for the D.C. Circuit on Monday night, less than an hour before a deadline for a brief outlining their appeal arguments, according to Politico.

Stone was sentenced in February to 40 months in prison and a $20,000 fine for charges that included lying to congressional investigators looking into Russian interference in the 2016 election. Prosecutors initially recommended imprisonment for seven to nine years, but the term was cut to a little more than three years by Attorney General William Barr.
