President Donald Trump denounced his former adviser, saying he “lost his mind” after leaving the White House. The comment came the same day New York magazine published excerpts of a new book in which Bannon criticizes Trump, his son, and the campaign.

As America gets back to work, a week of bitter cold is about to get worse. A winter storm threatens to inflict snow, ice and even colder temperatures from Florida to Nova Scotia. And this one may exceed your average nor’easter. It could turn into a bomb, short for bombogenesis, a phenomenon that occurs when a system’s central pressure drops steeply in 24 hours.

Shake Shack eyes some extra fries. Shares of the burger chain surged after a restaurant analyst said the Republican tax law will be a boon for the company. Tax reforms will help the broader restaurant industry, fueling same-store sales as consumers spend their savings on eating out, he wrote. The fast-food industry has been plagued by sluggish customer traffic, which has prompted intense competition on discounts and value meals.

Years after the first Chevrolet Volt and Nissan Leaf zipped off assembly lines, the market for plug-in vehicles in America is dominated by leases, not owners. Drivers now lease almost 80 percent of battery electric vehicles and 55 percent of plug-in hybrids, according to Bloomberg New Energy Finance.
