Didn't he say this already?
UPDATE: The tweet was accompanied by a Asa Hutchinson campaign press release saying his previously announced Republican gubernatorial campaign was underway. He said his first campaign report would show $350,000 in fund-raising, about the same as Democrat Bill Halter has said he'll report in contributions other than his own when first reports are filed. Halter has also put in $640,000 of his own money to hit $1 million.
It's early, but $350,000 is a light start for a race that is going to cost millions.
