Gov. Mark Dayton's interim campaign finance report showed that as a candidate, he built up a big debt: $3.9 million in loans from on Mark Dayton. He said Tuesday that he's got no plans to pay himself back.

"I doubt it. He's not planning on it," Dayton said.

Asked if his primary lender -- Mark Dayton -- had money left to fund a run for a second term, the governor said: "We'll see. In time, all things will be revealed."

It didn't take that long for such things to be revealed.

Tuesday afternoon, Dayton voluntarily released his 2010 tax return. He is the first governor in modern times to do so.

It showed he earned $671,724 last year, largely from capital gains, and paid $99,690 in federal taxes and another $50,000 in state taxes.

Dayton also released his tax return when he was running for governor.
