(CNN) - In his first campaign swing for Mitt Romney, Newt Gingrich this weekend called for party unity and a need to rally behind the likely GOP presidential nominee.
"We're now all on the same team, period," Gingrich said at the Georgia GOP convention Friday, according to the Columbus Ledger-Enquirer.

His comments came in a speech to a crowd that largely backed him when he won the Peach State’s primary in March.
Prior to dropping out of the race in early May, the former Georgia congressman and House speaker had previously vowed to stay in the running until the August convention to collect delegates and get out his message.
The strategy had some Republicans worried about party division, as Gingrich continually tried to court the more conservative factions of the GOP. On Friday, however, he said it was time for the party to come together and stand with Romney.
At the convention, he stressed the importance of making a Republican sweep not only in the Oval Office this November, but also in elections across the country.
"I am not for a narrow victory," he said. "I am for crushing the left in every single way."
His remarks were coded with stronger language for Romney than when he first endorsed the candidate during his suspension speech just weeks ago. At the time, Gingrich gave lukewarm praise, saying Romney was only conservative when compared to President Barack Obama.
In the following days, Gingrich began to step up his support and argued Romney had "earned" his way to represent the party his fall.
This weekend Gingrich also focused on Obama.
In an interview with CNN affiliate WTVM, Gingrich said the president's recent decision to back same-sex marriage - despite having once opposed it - qualified him as a flip-flopper.
"It's unfortunate he's so political, but it eliminates any attack on Romney about ever flip-flopping when you have Obama flip-flopping on something that big, and doing it immediately after the people of North Carolina voted 'no,'" Gingrich said. "It's almost like he was insulting the people of North Carolina."
Last week, North Carolina voted in favor of a constitutional amendment banning marriage and domestic partnerships for same-sex couples.
Gingrich's campaign appearances this weekend marked the first of a string of stops the former candidate will make for his former opponent. The two will share the stage together for the first time at the end of May at a Las Vegas campaign event.
