Donald Trump is telling Michigan voters that Republican presidential candidate Rick Santorum is a career politician who doesn't know how to create jobs.
Mitt Romney's campaign deployed an automated phone call from Trump Wednesday in Michigan, a state that has become a must-win for the former Massachusetts governor. Trump also recorded a Michigan radio ad for Romney.
The real estate mogul and reality show host endorsed Romney earlier this month.
On the call, Trump says he's tired of Santorum "pretending" to be the outsider in the race. Trump says the former Pennsylvania senator has been entrenched in the Washington culture for decades.
Trump calls Romney a good man who is working hard.
