With four weeks until Pennsylvania's primary, one presidential candidate has begun airing ads.
Sen. Barack Obama has two ads running in Pittsburgh, one positive and the other the Clinton campaign calls misleading and desperate.
Kevin Kinross, the Western Pennsylvania campaign director for Clinton, says the senator's ads aren't far behind.
One ad links Sen. Clinton to lobbyists by implication.
In a conference call Friday afternoon, the Clinton campaign assailed the lobbyist ad saying Obama's campaign does take money from those who work in companies that hire lobbyists as well as the partners of lobbyists.
