The House Intelligence Committee is finalizing legislation that would give the federal government an unprecedented role in helping banks, manufacturers and other businesses protect against cyberattacks.

The committee's approval, expected Wednesday, would pave the way for a floor vote next week. It's a defiant move by pro-business who are locking horns with and civil liberties groups. A similar proposal failed to gain traction in the Senate last year after the White House threatened to veto it.

But Committee Chairman Mike Rogers says the political calculus has changed because too many companies are losing money to Chinese hackers. He says there's a long line of companies willing to tell Congress quietly how they've lost their entire intellectual property portfolio to hackers.
