Papadopoulos, the first campaign aide sentenced in Special Counsel Robert Mueller's ongoing investigation, had said he was "deeply embarrassed" and acknowledged that his actions could have hindered the FBI agents' work.
The White House did not immediately issue a statement on the sentencing. I think the judge took everything into consideration.
According to Bloomberg News, the committee indicated that an investigator had been used to find Mifsud, who had disappeared for months, and was told the Maltese professor may be dead. "I would have preferred less time in jail, but that's OK".
Mueller told Trump's attorneys in March he was continuing to investigate the Republican president but did not consider him a criminal target "at this point", the Washington Post reported in early April.
Before the sentencing, his lawyer, Thomas Breen, told the court about how Trump had blasted the investigation as "fake news" and a "witch hunt" before Papadopolous met with the FBI and lied.
"I wanted to distance myself as much as possible - and Trump himself and the campaign - from what was probably an illegal action or unsafe information", he said.
He was the first ex-Trump aide arrested in the probe into an alleged Kremlin plot to sway the 2016 U.S. vote.
In a court filing, lawyers for Papadopoulos had argued for probation, saying he was "ashamed and remorseful" but wasn't trying to undermine the Russian Federation probe when he was "caught off-guard by an impromptu interrogation".
The only other defendant in the Russian Federation probe who has been sentenced is Dutch attorney Alexander Van der Zwaan.

The policy is a rule on the women's tour, but not the men's. "This is a good sign for Millman that he's got him breathing heavy". The break proved less useful in week one to players toiling on outside courts - far away from the sanctuary of a locker room.
As noted by USA Today, authorities thought that Papadopoulos could serve as a key informant, but it quickly became clear that was not the case.
US District Judge Randolph Moss sentenced foreign policy aide George Papadopoulos to 14 days in prison, acknowledging his guilty plea and his remorse, but noting that he "lied in an investigation that was important to national security".
During Friday's hearing, Papadopoulos' attorney Thomas Breen went out his way to praise the Federal Bureau of Investigation, and he also criticized Trump for calling the Russian Federation probe fake news and a witch hunt. Said George was "naive" and "a fool". He received a sentence of 30 days in prison and a $20,000 fine.
Papadopoulos pleaded guilty in October to making false statements to the investigation.
The Russian outreach to Papadopoulos was part of a sweeping active measures campaign aimed at the United States that also included overtures toward other political operatives, cyberattacks, agitation on social media and more.
Breen told reporters outside court, "I think we're all somewhat satisfied at this point in time that they know Russian Federation meddled in the election".
Papadopoulos was once described as a "coffee boy" to the Trump campaign.
