Washington (CNN) – Less than twenty-four hours after his admission that he misrepresented his military record, the campaign of Senate hopeful Mark Kirk has released two ads that slam his Democratic opponent.
Kirk, the Republican nominee hoping to capture President Obama's old Senate seat, admitted during a news conference Tuesday that he had mischaracterized his military record.
"I am not perfect, and I was careless. I will do better and make sure this never happens again," Kirk said.
But now his campaign is striking back at Alexi Giannoulias, the Democrat who earlier this year waged a public relations battle of his own following the failure of a bank owned by his family.

But that's where the similarities end.
"Risky" focuses on the failure of Broadway Bank, where Giannoulias was employed before being elected Illinois State Treasurer.
"Alexi Giannoulias is only 34 years old," the ads narrator says." But what a 34 years it's been."
The 30-second spot then turns to loans made while Giannoulias was employed at the bank and his investment decisions as state treasurer before the narrator asks, "Alexi Giannoulias. Trust him with your money?"
"Stand" makes reference to the oil spill currently plaguing the Gulf of Mexico, and highlights Kirk's environmental record, which includes efforts to stem the pollution of Lake Michigan.
"Mark Kirk won praise for helping stop BP when it tried to pollute Lake Michigan," the narrator says.
The Giannoulias campaign shot back Wednesday afternoon, releasing a statement and an ad of their own.
"By his own admission, Congressman Mark Kirk has lied repeatedly about his military record and other parts of his professional life, and now he is lying about Alexi," Giannoulias spokesman Matt McGrath said. "After promising the people of Illinois a renewed commitment to honesty and transparency, Congressman Kirk couldn't even make it a single day before lying again."
Titled "On and On," the Giannoulias ad is a video compilation of instances in which Kirk has stretched the truth about his military record, coupled with news reports detailing the allegations against the five-term congressman.
Kirk and Giannoulias are seeking the seat currently held by Sen. Roland Burris, who decided not to pursue the Democratic nomination.
