On TransCanada: Sierra Club Nebraska asked the U.S. Attorneys Office on Wednesday to investigate TransCanada, Inc. for contributions the oil company made to Gov. Dave Heineman and Attorney General Jon Bruning. Heineman and Bruning each returned $2500 to the company after learning of a federal ban on foreign contributions. TransCanada says the checks were intended to come from their U.S. subsidiary. How big of an oversight is this? Is it a bump in the road for the Keystone XL Pipeline or something more? On the Wheel Tax: A group of Sarpy County leaders asked Nebraska Attorney General Jon Bruning to help them investigate the legality of Omaha's new commuter wheel tax. Bellevue City Council president Carol Blood says there are state laws in both Nebraska and Iowa that could prohibit the fee. Omaha's legal teams says they're good. Bellevue thinks they're not. What are the chances this goes through? And if it doesn't, what happens to the city's budget?
