Obama set for pardon frenzy as he leaves office... May include Clinton and Bergdahl...
A Rastafarian prophet, a former Taliban captive and thousands of minor drug traffickers have one thing in common: Their names have been submitted to President Barack Obama for clemency before he leaves office in two weeks.
Some US presidents have used this regal power of leniency in a pointed way near the end of their term in office.
On the last day of his term in 2001, Democratic president Bill Clinton granted pardon in a highly controversial move to late fugitive trader Marc Rich, whose ex-wife had been a major donor to Democrats.
Sixteen years later, Obama is fielding pressure from all sides to grant unlikely pardons or commutations of sentences to people whose supporters say have been unjustly sentenced or sought out by the justice system.
Among them is Bowe Bergdahl, a US Army sergeant held captive for five years by the Taliban before his release in a prisoner swap, who is due to be court-martialed for desertion.
Leonard Peltier, a Native American activist convicted for the 1975 deaths of two FBI agents in what his supporters say was a setup, is also hoping to enjoy Obama's good graces.
Then there's Edward Snowden, who made the shattering revelation in 2013 of a global communications and internet surveillance system set up by the United States.
The 33-year-old, a refugee in Russia, is backed by numerous celebrities like actress Susan Sarandon and singer Peter Gabriel, as well as Amnesty International and the American Civil Liberties Union.
- Preventive clemency -
If Obama fails to pardon Snowden, his supporters say he may face the death penalty under the incoming administration of Republican Donald Trump, who has called him a "terrible traitor."
In another leak case, Chelsea Manning is serving a 35-year sentence in solitary confinement for handing 700,000 sensitive military and diplomatic documents to WikiLeaks, some of them classified.
Activists say her sentence is excessive and point to the psychological frailty of the transgender soldier who has already made two suicide attempts.
Even though the White House has dismissed a possible pardon for Snowden and Manning, their supporters are still hoping for a final magnanimous gesture from a president about to leave the constraints of his high office on January 20.
But both cases present unique challenges: Snowden has yet to be sentenced and merely faces espionage charges in the US, while Manning has an appeal pending before military court.
The US Constitution allows a president to pardon "offenses against the United States" and commute -- either shorten or end -- federal sentences.
Obama has so far granted 148 pardons since taking office in 2009 -- fewer than his predecessors, who also served two terms, George W. Bush (189) and Bill Clinton (396).
But he has surpassed any other president in the number of commutations, 1,176.
- Or posthumous mercy -
Most of those who benefited from the president's clemency were minor drug dealers no longer considered a threat.
Obama has promised to use his clemency powers to help serve penal justice, rather than to grant special favors.
"I don't think we will see high-profile names on the list of President Obama's final clemency grants," Mark Osler of the University of St. Thomas told AFP.
"It is most likely they will be the types of cases he has previously commuted: nonviolent narcotics offenders."
He noted that last-minute clemency is a recent phenomenon.
"Up until President Clinton, they usually spread them out over their full term. Hopefully, in the future presidents will return to that practice, which seems less prone to abuse," Osler said.
Presidents can theoretically pardon people before they are even sentenced.
In 1868, president Andrew Johnson granted a "full pardon and amnesty" to Confederates of the 11 southern states who unsuccessfully fought the Civil War to secede from the union.
Citing this precedent, some have urged Obama to preventively pardon defeated Democratic presidential candidate Hillary Clinton over her use of a private email server while serving as secretary of state in light of Trump's threats to have her prosecuted.
Obama could also be tempted to grant amnesty to his onetime "favorite general," James Cartwright, who lied to the FBI about his discussions with journalists about Iran's nuclear program.
Some pardon requests can be far-fetched, such as one for the late Marcus Garvey, a Jamaican political leader who backed Pan-Africanism and helped inspire the Rastafarian movement.
Supporters are seeking a posthumous pardon for Garvey, who died in 1940. He was convicted of mail fraud in the United States and later deported back to Jamaica. Some Rastafarian followers consider him to be a prophet.
