Stone is an old friend and adviser to Trump.
On Tuesday, the 67-year-old Stone was scheduled to appear in a Federal prison in Georgia to begin serving a three-year, four-month sentence. He was convicted of lying under oath to US lawmakers investigating Russian interference in the 2016 US election, threatening witnesses and destroying evidence.
A veteran of the Republican Party, Stone has been friends with Donald Trump for several decades.
Asked earlier on Friday, if he was going to pardon Stone, Trump said: “I will consider this issue. I think that Roger stone was mistreated, as many people were.”
Commutation of a sentence does not overturn a conviction, as a pardon does.
Democrat Adam Schiff, head of the House Intelligence Committee, condemned the President’s decision, saying that Trump showed that “there are two justice systems in America: one for his criminal friends, the other for everyone else.”
