ST. PAUL — Minnesota Republicans say the state Department of Revenue shouldn’t have cited Gov. Mark Dayton’s role in enacting recent tax breaks in a letter sent to people who might benefit.

Republican state senators argued Wednesday that use of Dayton’s name in the letter turned it into a political document. The letter went to some people who qualified for additional deductions or credits because of a bill passed in March.

It starts with a message that Dayton signed the bill and then offers routine information about claiming the breaks.

A similar 2010 letter from the Revenue Department included then-Republican Gov. Tim Pawlenty’s name.

Dayton spokesman Linden Zakula called the GOP criticism “another baseless attack” and said nothing in Minnesota law prohibits the Revenue Department from mentioning a governor’s name in an official letter.
