Whitmer visited Biden Sunday, according to two high-ranking Michigan Democrats who spoke on the condition of anonymity because they were not authorized to discuss the matter publicly. The first-term governor of the battleground state has long been on his short list of possible running mates.
Flight records show a chartered plane left Lansing’s Capital Region International Airport for Delaware Coastal Airport at 5:33 p.m. and returned at 11:16 p.m.
The development comes as Whitmer has been increasing mandates on Michiganders to blunt the spread of coronavirus, and said in an interview that she was spending “100 percent” of her energy on being governor.
She also tightened restrictions on masks and self-lockdowns.
