Washington ( CNN ) -- Sen. Kay Hagan is punching back at her opponent after getting slammed by Republicans this week over missing a classified briefing on ISIS and other security threats to attend a fundraiser . In a TV ad released first to CNN on Friday , the North Carolina Democrat rebukes GOP attacks , plays up her voting attendance record on the Armed Services Committee and slams her rival North Carolina House Speaker Thom Tillis as a `` hypocrite . '' Hagan admitted earlier this week that she missed an Armed Services Committee meeting to attend a fundraiser . What she did n't tell reporters in that post-debate press conference was that the meeting was in fact a classified briefing on ISIS and other national security threats with the Director of National Intelligence James Clapper . The revelation has given Republicans fresh fodder to slam Hagan 's already shaky attendance record at Armed Services Committee hearings , but Hagan 's campaign is looking to spotlight Tillis ' own irregular attendance record . Hagan 's ad spotlights Tillis ' record of missing legislative work in favor of fundraising , which even prompted his hometown paper to call for Tillis ' resignation -- a clip featured in the latest Hagan ad . The ad also claims Tillis has `` no military plan to take out ISIS '' and plays up Hagan 's 98 % voting attendance record and says she `` leads hearings on eradicating terrorists like ISIS . '' Hagan 's TV spot was released the same day the Karl Rove-tied Crossroads GPS pushed an ad playing back Hagan 's post-debate statement . `` You know , there was one , '' Hagan told reporters on Tuesday . `` And what had happened at that hearing , it was scheduled early in the day , and then votes were scheduled , and then that hearing had to be postponed later that day . So yes , I did miss that one . '' That statement rolls uncut for 14 seconds in the 30-second sport after viewers are led in with footage of masked gun-wielding ISIS militants while a narrator talks about ISIS 's `` mass murder '' campaign , threats of terrorism on U.S. soil and beheading of Americans . `` Hagan skipped the hearing for a fundraiser , '' the ad closes . And when confronted with his own voting record , Tillis deflected a question about his habit of putting cash campaigning before his State legislature duties . `` Quite honestly , if I had anything approaching the seriousness of the threat of ISIS , I would have canceled anything I was doing . '' `` There is nothing more important than receiving briefings on our national security , '' Tillis told reporters on a conference call Wednesday . `` It 's the top responsibility of every Member of Congress . Senator Hagan has failed to do her job . What is her excuse for not showing up to work over half the time ? '' The Democratic senator 's campaign had earlier confirmed that Hagan attended less than half of the committee 's 49 public hearings in the last two years , but that none of those absences were tied to fundraisers . Faced with questions Wednesday about why it had n't revealed that a fundraiser trumped a hearing , the campaign insisted it had n't been not forthcoming because that list of missed hearings did n't include closed-door briefings -- like the one she missed Feb. 27 to attend a New York fundraiser . Republicans immediately pounced on the report that Hagan missed a crucial briefing on the ISIS threat , an issue that now has the potential to swing the already neck and neck race in Tillis 's favor . Polling over the last week has shown Hagan maintaining a razor-thin two- to four-point lead over her challenger . DSCC ad : Tillis in Koch brothers ' pocket . Charges that incumbents have missed hearings , briefings , votes , and other official work are popping up in a several closely-fought Senate races this year . And in the Republican-leaning Tar Heel state , which boasts a large military population , Tillis is betting Hagan 's absences from a national security hearings and at least one intelligence briefing will hurt the first-term senator . Democratic campaign operatives in Washington , who are already battling headwinds in their effort to keep the Senate in Democratic control , conducted private polling on the question so they could fully understand its impact . The results showed the issue is very potent and could damage even seasoned candidates .
