Washington (CNN) - President Barack Obama's campaign has made a very small ad buy in Minnesota to counter a new purchase by Mitt Romney in the state, an Obama campaign official and a Republican ad tracking source told CNN.
Earlier Friday a Romney campaign official confirmed it had bought a small amount of television ad time in Minneapolis. Two ad tracking sources told CNN the Romney buy was about $30,000 and would run Saturday through Tuesday. The amount of the Obama buy has not been disclosed.

One Democratic source tracking media buys dismissed Romney's move, calling it a "press release" trying to generate buzz about a tightening race that he does not believe exists there.
Republicans, however, say they feel there is some movement in the state helping them. A Romney campaign aide confirmed the buy saying "Our map is expanding." Romney advisers point to recent partisan polling showing a tightening race in Minnesota with the margin in single digits.
Minnesota has been considered a safe Democratic state for many years in presidential races. But the Obama campaign did send Jill Biden, the wife of the vice president, to the state for a visit earlier this week.

Romney has gotten some support already there as one Republican-leaning group, American Future Fund, has been on the air recently spending more than $1.5 million criticizing President Obama's record and touting Romney.
Another benefit in purchasing time in Minneapolis is that you get your message seen in parts of Wisconsin. The Minneapolis market reaches approximately 7 counties of neighboring Wisconsin, which is about 5% of the state where there is a fierce ad battle ongoing. CNN rates Wisconsin as a "toss-up" state.
The Obama campaign had previously put a small amount towards cable ads in Minneapolis and radio commercials in the Duluth area.
