Gov. Perry formally endorsed Mitt Romney Thursday, a day after news broke that Newt Gingrich would be dropping out of the race next week. Perry endorsed Gingrich when he withdrew from the race in January.

Perry said Romney "earned his status" as the likely GOP nominee, "through hard work, a strong organization and disciplined message." There was no mention of whether or not Perry would be campaigning for Romney.

"Mitt Romney has earned the Republican Presidential nomination through hard-work, a strong organization, and disciplined message of restoring America after nearly four years of failed job-killing policies from President Obama and his administration," said Governor Perry. "So today I join the many conservative Republicans across the nation in endorsing Mitt Romney for President and pledge to him, my constituents and the Republican Party that I will continue to work hard to help defeat President Obama. American jobs, economic stability and national security depend on electing a new president. Mitt ‘s vision and record of private sector success will put America back on the path of job creation, economic opportunity and limited government."
