Republicans in the House of Representatives are leading a push to protect America's infrastructure from cyber-attacks.  They're debating the Cybersecurity Enhancement Act on Capitol Hill Thursday and a vote is expected Friday. 

The bill, written by the Republican chairman and top Democrat on the House Intelligence Committee, would get the private sector and government to share information to thwart attacks from foreign governments, cyber-criminals and terrorist groups. 

Supporters of the Cybersecurity Enhancement Act say it will protect critical infrastructure and corporations from electronic attacks.

Compliance to the legislation would be voluntary, but the White House says the law fails to protect Americans' privacy.  The Obama administration contends the measure too broadly protects the cooperating companies from liability.

The U.S. Chamber of Commerce and other business groups oppose requiring cyber-security standards.  They are joined by civil liberties groups, who say it could lead to the government spying on Americans.

Similar legislation has stalled in the U.S. Senate.
