​Former Vice President Joe Biden released a video touting the achievements of the Obama administration and showing him and the former president exchanging high-fives just hours before the third Democratic presidential debate Thursday evening.

“Barack Obama was a great president. We don’t say that enough​,” Biden wrote in the Twitter posting linking to the video.

​In it, he’s shown at a campaign rally, saying Obama “has character, courage and vision. ​H​e was a president our children could and did look up to.​”

Biden, who has been criticized for playing on his relationship with Obama during the debate and on campaign stops, said he was “proud to serve as his vice president, but never more proud than the day we passed health care.”

The video went on to list the administration’s achievements, including ObamaCare, “led on marriage equality,” “rescued the auto industry,” and the “Iran nuclear deal.”

​Still photos showed them embracing and high-fiving.

The Democratic presidential candidates have criticized Biden for riding Obama’s coattails.

In the first debate in Detroit, Biden was put in the position of defending the administration’s legacy on stage as the other candidates tore into ObamaCare and the high number of deportations during his tenure.

Biden said he hadn’t expected that.

“I was a little surprised at how much incoming there was about Barack, about the president,” Biden said. “I don’t think there’s anything that he has to apologize for. It kind of surprised me, the degree of the criticism.”
