TUCSON, Ariz. — A Tucson physician says he’ll challenge U.S. Rep. Martha McSally again for the Arizona Congressional District 2 seat.

Dr. Matt Heinz announced Tuesday that he’s entering the race for next year’s election.

Heinz got 43 percent of the vote in November 2016, but McSally won a second term in her Tucson-area swing district.

In a statement, Heinz says the district needs a change in leadership and the Republican McSally “has been too busy circling the wagons” around President Donald Trump.

Heinz is a Democrat who works as an emergency room physician.

At least six other candidates have already announced their campaign to seek the Democratic nomination in the 2nd Congressional District.
