Some Senate Democrats are seizing on Burger Kings Canadian doughnut chain Tim Hortons to renew their calls for Congress to ban corporate inversions. The merger will involve relocating the companys headquarters to Canada, meaning it will not have to pay U.S. taxes on its foreign earnings. Michigan Democratic Sen. Carl Levin said in a press release on his website, Congress cant afford to wait any longer to put a stop to tax dodging through this kind of merger. Levin also predicted a strong public reaction against Burger King that could more than offset any tax benefit it receives. However, executives at Burger King argue that the move is not motivated by taxes, but rather is an acknowledgement of the primary role that Tim Hortons will play in the combined company.
