Washington (CNN) - Rep. Mark Kirk, the Illinois Republican seeking President Obama's old Senate seat, raised $2.2 million in the first quarter of 2010, and has more than $3 million in the bank, his campaign said Wednesday.
"Illinois voters have a clear choice in this election to change direction, create jobs and restore integrity to the State of Illinois," the five-term congressman said in a written statement.
Kirk is set to face Democratic nominee and Illinois State Treasurer Alexi Giannoulias in November. Current Illinois Sen. Roland Burris, a Democrat, will not seek a full term for the seat he was appointed to after Obama became president.
The Giannoulias campaign has not released its own fundraising totals for the first quarter, but did respond to the Kirk figures.
"Mark Kirk's campaign fundraising reports should be looked at two ways: as an invoice for services rendered on behalf of corporate special interests, and as a promissory note for future obstruction of President Obama's agenda and on behalf of those interests," said Giannoulias campaign manager Michael Rendina in a statement.
The Illinois race has already seen a flurry of attacks from both campaigns, and even the White House has weighed in.
In March, Obama senior adviser and Chicago native David Axelrod gave an interview with the Chicago Sun-Times, where he criticized Kirk for telling a group of Republicans that if elected, he will, "lead the effort to repeal this [health care] bill."
Giannoulias has been the target in recent months of a series of attacks stemming from time he spent as a loan officer at Broadway Bank, a firm run by his family that he says is now facing insolvency.
