'Freudian slip': Biden accidentally calls Obama 'Trump'

"Back in 2009, during the so-called Great Recession, the president asked me to be in charge of managing that piece, then-President Trump," he said, quickly recovering. "Excuse me, Freudian slip. That was the last president."

Biden said in his speech that "buy American" in recent years had become a hollow promise, an apparent reference to policies pushed by his predecessor, Republican President Donald Trump.

Biden's trip to the Lehigh Valley area took place as congressional negotiators back in Washington reached a bipartisan deal on infrastructure aimed at rebuilding roads and bridges and the like.

Biden met local members of the United Autoworkers Union, which represents 85% of the 2,500 workers at Mack Trucks' Lehigh Valley plant, and received a briefing on the new electric-powered garbage truck the company is piloting in New York City and North Carolina.
