Unger said the challenge is to protect not only people, but also the sensitive data and information in Capitol offices.
"We want to make sure that anyone that's working on the Capitol grounds, that we know who they are," Unger said.
The bill does not require background checks for state employees, only contract workers on Capitol grounds — such as the ones hired through Goodwill.
West Virginia's state Capitol building is one of the most open government buildings in the country.
Whereas most county courthouses or other state office buildings have metal detectors or key-card-only access to most areas, visitors at the state Capitol can wander around most areas without having to clear any type of security.
Unger said that's something lawmakers want to maintain.
"It's the people's Capitol, and we want to make sure that we keep it as open as possible for the public," he said.
But he said the incident with Dailey shows that lawmakers have to maintain some balance between openness and security to protect officials and the public.
"We're looking at ways to primarily ensure that the public's safe," he said, "that when they come here they don't have to worry about some types of threats — but also making sure that it remains open.
"We're trying to keep that balance, and this bill is one way of doing that," he said.
The Senate will vote on the bill during today's floor session. It still must be approved by the House of Delegates and signed by the governor before becoming law.
