Republican presidential front-runner Mitt Romney brought two of his sons with him Friday to tape an interview with Mike Huckabee, his former rival for the 2008 GOP nomination.

Romney press secretary Andrea Saul tweeted a picture of Romney, Huckabee, Romney’s son Tagg and Tagg’s son Joe.

The family visit comes amid speculation that Huckabee might consider endorsing Romney for the nomination, despite their rocky relationship in the past.

Huckabee, a former Arkansas governor, is an outspoken Evangelical and has clashed with Romney’s Mormon beliefs in the past. His endorsement would likely improve the former Massachusetts governor’s chances with socially conservative voters.
