U.S. President Donald Trump on Wednesday granted full pardons to former campaign manager Paul Manafort and former adviser Roger Stone, sweeping away the most important convictions made under the long-running Russia election probe.

Trump also issued a full pardon for Charles Kushner, a real estate developer and the father of Trump's son-in-law, Jared Kushner.

It was the second wave of pardons Trump has issued in two days. The announcement came just after Trump arrived in Palm Beach, Florida, for the holiday season, with Jared Kushner on the Air Force One flight with him.

In total, Trump issued on Wednesday full pardons to 26 individuals and commuted part or all of the sentences of an additional three people.

Facing the end of his term on Jan. 20, Trump has now granted full pardons to four major figures from U.S. Special Counsel Robert Mueller's investigation into Russian meddling in the 2016 presidential campaign.

Besides Manafort and Stone, Trump has pardoned former national security adviser Michael Flynn and former adviser George Papadopoulos.

The Manhattan district attorney's office, which has been trying to prosecute Manafort in New York for mortgage fraud and other alleged crimes, said it would continue to pursue an appeal for its case, which was dismissed on double jeopardy grounds.

"This action underscores the urgent need to hold Mr. Manafort accountable for his crimes against the People of New York as alleged in our indictment, and we will continue to pursue our appellate remedies," said Danny Frost, spokesperson for the office.

The Manafort pardon spared the long-time Republican operative from serving the bulk of his 7 1/2-year prison term.

Manafort, 70, was among the first in Trump's inner circle to face charges brought by Mueller as part of his probe into Russian interference in the 2016 presidential election.

In a statement relayed by his lawyer, Manafort expressed his appreciation to Trump.

"Mr. President, my family & I humbly thank you for the Presidential Pardon you bestowed on me. Words cannot fully convey how grateful we are," he said.

Stone was convicted in November 2019 by a Washington jury of lying under oath to lawmakers also investigating Russian interference in the 2016 election.

Trump commuted his sentence in July, a day before Stone was due to begin serving a term of three years and four months. Stone, in a statement, thanked Trump for "completely erasing the criminal conviction to which I was subjected in a Soviet-style show trial on politically-motivated charges."

Charles Kushner was sentenced to two years in prison after pleading guilty in 2004 to 18 counts of tax evasion, witness tampering and making unlawful campaign donations.

In an unusual twist, the man who prosecuted Charles Kushner was Chris Christie, now the former governor of New Jersey, who also has served as an adviser to Trump.

Christie was quoted by CNN as saying Charles Kushner's case was "one of the most loathsome, disgusting crimes" he prosecuted. During the case, Charles Kushner admitted to smearing his brother-in-law, who had cooperated with prosecutors, by hiring a prostitute to have sex with him in a motel room, then sending a secretly recorded video of the encounter to the man’s wife, Charles Kushner’s own sister.
