State officials say they are confident the technology is secure.
"Democrats from coast to coast threw everything they had at this race, and Karen would not be defeated", House speaker Paul Ryan said in a statement.
Ms Handel has handled Mr Trump gingerly.
Candidates in Georgia's 6th Congressional District race Republican Karen Handel, left, and Democrat Jon Ossoff prepare to debate Tuesday, June 6, 2017, in Atlanta. But Trump isn't everything, and independent of anything he's done, Republicans have created some serious vulnerabilities for themselves.
Handel is the latest in a line of Republicans who have represented the district since 1979, beginning with Newt Gingrich, who would become House speaker.
Regardless, do not read too much in to the early vote results too early. "I would feel my voice is heard". "But it's extremely concerning that Congress is moving forward with this".
Democrats need to flip 24 Republican-held seats to reclaim a House majority; winning a conservative district like this one would embolden the party and serve notice to Republicans that a Democratic takeover is possible.
Karyn Dolan was still mulling her decision in Georgia's razor-tight House district race as she exited her local polling station Tuesday morning in scrubs after her night shift at a nearby hospital.
A recent poll by the Atlanta Journal-Constitution revealed only one-quarter of District 6 voters said they favored the House's new plan. My son is self-employed, and he'd have to spend a fortune for health care if he couldn't get on the exchanges. Handel, a republican, is a 55 year old former Georgia Secretary of State.
So, Pave It Blue members are now campaigning for Ossoff and doing it with the apparently effective help of dinosaur costumes.
Handel had also been invited on "New Day" but declined to appear.
Even those not actively involved in the campaign have noticed. A little over 27,000 absentee mail ballots were submitted, with David Wasserman of Cook Political Report noting that Ossoff needed to win at least 80 percent of those.
On its own, Senate Republicans' health bill may be a political millstone around Handel's neck, but not necessarily a knock-out blow.
Last month, Republican Greg Gianforte won a special congressional election in Montana, despite being charged with assaulting a United Kingdom reporter.

"Folks across the political spectrum and women across the political spectrum are exhausted of politicians trying to make healthcare choices for them and impose their own views", Ossoff told BuzzFeed in an interview. But, ironically, high turnout could be helping Handel. Planned Parenthood's Action Fund has had a team of 40 canvassers go door-knocking every day of the election for Ossoff in the Sixth. Voters care about a lot.
"There is no doubt in my mind that the shooting at the GOP Congressional Baseball practice has had an impact, but I don't see that it is the impact that most pundits expect", TFG Senior Strategist Robert Cahaly said.
Ossoff, a "documentary filmmaker" by trade, boasts a number of A-list donors including Jessica Lange, Sam Waterston, Kristen Bell and Kyra Sedgwick, as well as some B- and C-listers like Rosie O'Donnell, Jon Cryer, Chelsea Handler and Sean Daniel. "If a woman can't stand up for other women, then that woman shouldn't be in office".
