US President Donald Trump on Tuesday pardoned 15 people, including Republican allies, a 2016 campaign official ensnared in the Russia probe and former government contractors convicted in a 2007 massacre in Baghdad.

On Tuesday, Trump issued the pardons even as he refused to publicly acknowledge his election loss to Democrat Joe Biden, who will be sworn in on Jan. 20.

Those pardoned on Tuesday included former Republican Reps. Duncan Hunter of California and Chris Collins of New York, two of the earliest GOP lawmakers to back Trump’s 2016 presidential campaign. Trump also commuted the sentences of five people, including former Rep. Steve Stockman of Texas.

Trump announced pardons for two people entangled in special counsel Robert Mueller’s Russia investigation. One was for 2016 campaign adviser George Papadopoulos, who pleaded guilty to lying to the FBI about a conversation in which he learned that Russia had dirt on Trump’s Democratic opponent, Hillary Clinton. The president also pardoned Alex van der Zwaan, a Dutch lawyer who was sentenced to 30 days in prison for lying to investigators during the Mueller probe.

The pardons drew criticism from top Democrats. Rep. Adam Schiff, D-Calif., the chairman of the House Permanent Select Committee on Intelligence, said the president was abusing his power.

“Trump is doling out pardons, not on the basis of repentance, restitution or the interests of justice, but to reward his friends and political allies, to protect those who lie to cover up him, to shelter those guilty of killing civilians, and to undermine an investigation that uncovered massive wrongdoing,” Schiff said.

Last month, Trump pardoned former national security adviser Michael Flynn, who had twice pleaded guilty to lying to the FBI, and months earlier commuted the sentence of another associate, Roger Stone, days before he was to report to prison.
