(MCT) — DETROIT — President Barack Obama visited Detroit Diesel’s engine plant in Redford Township Monday to talk about the company’s $120 million investment and to promote his plan to address the fiscal cliff.

But Obama, whose re-election was aided by strong union support, pivoted about half-way through his speech to address right-to-work legislation. “What we shouldn’t be dong is taking away your rights to bargain for better labor agreements,” Obama said. “These so called right-to-work laws, they don’t have anything to do with economics, they have to do with politics.”
