Illinois Senate candidate Alexi Giannoulias (D) plans to respond to the two TV ads released by his Republican rival this week with a TV spot of his own.

On Thursday, a Giannoulias spokeswoman told The Ballot Box the campaign decided to refrain from airing the ad over the holiday weekend because the ad rates were too high.

On Friday, a Giannoulias spokeswoman told The Ballot Box that "the ad will begin airing next week because, with the holiday weekend, not many families will be home."

The ad (seen below) will go up on the air next week.

The ad focuses on the recent scandal surrounding Rep. Mark Kirk's (R-Ill.) military record.

The five-term congressman had earlier released two ads that hit Giannoulias for his work at his family's failed bank and his connection to a lobbyist for BP.

The Giannoulias ad, titled "On and On," features a clips from Kirk giving a speech on the House floor, and sound from TV news segments playing over chyrons of newspaper and magazine reports that say Kirk was "caught in a lie" about his military service record. It was released online Wednesday.

Adelstein Liston produced the spot.

Meanwhile, Kirk's campaign announced Thursday it raised some $2.3 million in the second quarter — its largest quarterly haul to date — according to a release. Despite the rough treatment in the press, Kirk raised more than $1 million in June. He's left with close to $3.9 million in the bank after the double ad buy.

—An earlier version of this post indicated incorrectly that the ad was airing starting Thursday.
