(Washington, D.C.) -- Oil companies are making record profits. Chevron has announced a 75-billion dollar stock buyback. Oregon Senator Ron Wyden says oil companies are making huge profits on the backs of Americans who are struggling to buy food, medicine and travel. Wyden has proposed the Taxing Big Oil Profiteers Act which would raise the tax on oil company stock buybacks to 25-percent. He says it's important to put a check on price gouging and windfalls for wealthy shareholders.
