(AP) Officials say they will look into a tax break for Maryland residents received by Alaska’s Republican U.S. Senate candidate. Alaska Public Radio Network reported that Dan Sullivan owned a home in Bethesda, and the Alaska Democratic Party chairman asked Maryland officials to look into Sullivan’s eligibility for the tax break. It requires owners to say the home is their principal residence. Chairman Mike Wenstrup questioned if Sullivan could receive the exemption while voting in Alaska. Robert E. Young, director of the Maryland Department of Assessments and Taxation, said he didn’t get the letter yet but has a legal obligation to investigate the claim. The Sullivan campaign declined to comment to the network, but his website says he considered his time outside Alaska a temporary duty assignment.
