Washington (CNN) - Rep. Mark Kirk, the Republican hoping to capture President Obama's old Senate seat, raised $2.3 million dollars in the 2nd quarter, his campaign said Thursday.
It is the most successful quarter to date for the five-term congressman who apologized recently for mischaracterizing his military record.
The 2nd quarter totals include a more than $1 million haul in month of June, brought in as the controversy over the candidate's military record was unfolding.
"We are humbled by the outpouring of support from families across Illinois," Kirk campaign spokesperson Kirsten Kukowski said in a statement. "With unemployment in Illinois higher than the national average, we need leaders who will turn our economy around and put Illinois back to work."
Despite television buys for two ads that debuted on Wednesday, the campaign reported $3.9 million in cash on hand.
Kirk's Democratic opponent, Illinois state treasurer Alexi Giannoulias, has not yet reported 2nd quarter numbers, but was the beneficiary of a high profile fundraising event headlined by Vice President Joe Biden in June.
Kirk and Giannoulias are seeking the seat currently held by Sen. Roland Burris, who decided not to pursue the Democratic nomination after being appointed to the seat by former Gov. Rod Blagojevich.
At the beginning of June, two well-respected non-partisan political handicappers rated the race as competitive. The Cook Political Report said the contest leaned Republican, while the Rothenberg Political Report rated the race as toss up/tilt Republican.
