In April, Santos was sentenced to seven years after a judge told him: “You got elected with your words, most of which were lies.”
He reportedly cried in court and begged for forgiveness, saying: “I cannot rewrite the past, but I can control the road ahead.”
Prosecutors argued that the novice politician had lied about his background and misused campaign funds to finance his lifestyle.
In his post, Trump reasoned his decision by criticising a Democratic lawmaker, Senator Richard Blumenthal, who he accused of lying about his service in the US military.
“This is far worse than what George Santos did, and at least Santos had the Courage, Conviction, and Intelligence to ALWAYS VOTE REPUBLICAN!” Trump wrote.
Trump has previously called for an investigation into Blumenthal over the claim. The Democrat has acknowledged that he misspoke on numerous occasions about his time in the military but has said the mishaps are more than a decade old.
“This allegation of 15 years ago has been really rejected by the voters of Connecticut three times, overwhelmingly reelecting me,” Blumenthal told CNN earlier this month.
