These U.S. companies are still doing business in Russia

But Russians are still getting their fill of American fare like burgers and pizza, as Hard Rock Cafe and Sbarro are among the more than two dozen U.S. corporations that continue to do business as usual in Russia.Twenty-seven U.S-based companies are defying calls to exit or curtail their activities in Russia, according to a running tally by Yale University management professor Jeffrey Sonnenfeld and his research team.While Starbucks and McDonald's have both announced their complete withdrawals from Russia in recent days, Hard Rock continues to operate its Hard Rock Cafes in Moscow and St. Petersburg, Russia. We will continue to provide updates and do what we can to help our team members, customers and suppliers get through this situation safely as we hope for a peaceful resolution," the company stated.Another company, Des Moines, Iowa-based food additives supplier Kemin Industries, defended its ongoing operations in Russia as doing its part to offset hunger, including in Ukraine and Russia."With the long-held conviction that weaponizing food is abhorrent, Kemin continues to do its part to help feed people and assist crippling food insecurity magnified during a time of war," the company said in a statement to CBS MoneyWatch.
