GRAND RAPIDS, MI — U.S. Rep. Justin Amash has reiterated his opposition to a cybersecurity bill as the House of Representatives prepares to consider the controversial measure.

Amash, R-Cascade Township, wrote on Facebook he would vote against the Cyber Intelligence Sharing and Protection Act, or CISPA, because of overriding privacy concerns.

A message was left seeking comment from a spokesman for Rep. Bill Huizenga, R-Zeeland, though Huizenga indicated earlier this year he was "comfortable" with CISPA.

CISPA, sponsored by Michigan Rep. Mike Rogers of Brighton, is on the House's docket for Wednesday, according to the official House schedule.

Critics have called the legislation, which seeks to streamline the sharing of data between private corporations targeted by cyberattacks and the federal government, a serious overreach of government power.

On his Facebook, Amash wrote he would oppose CISPA when it is brought to a vote.

"The bill grants corporations and other entities broad immunity to share your personal and confidential data (e.g., e-mails) with the government," Amash wrote. "CISPA overrides contracts and even federal and state privacy laws."

CISPA has been likened to two widely unpopular bills considered by Congress during the 2011-12 session: the Stop Online Piracy Act, or SOPA, and the Preventing Real Online Threats to Economic Creativity and Theft of Intellectual Property Act, or PIPA.

Those bills, which sought to curtail Internet piracy and illicit trafficking of intellectual property, died in Congress after a groundswell of online activism from critics who said they threatened innovation and amounted to government censorship.

Supporters, however, say bills like CISPA are needed because of data showing mounting cyberattacks on American corporations by international agents.

During TV interviews earlier this year, Rogers, who chairs the House Intelligence Committee, contended 95 percent of private sector networks are "incredibly vulnerable" to cyberattacks.

Huizenga told MLive in February that he is not an "automatic yes" on any bill, but felt comfortable with CISPA because he'd been apprised of threats facing corporations.

There are threats "not only to government computers, but to what some people would argue are some pretty central networks to how things are running," Huizenga said in February.

"We've seen attacks on Wall Street, we've seen attacks on finances, on credit cards, we've seen attacks on things that are part of our daily lives," he added.

CISPA is similar, but not identical, to an executive order signed by President Barack Obama in February that encourages federal agencies to work with corporations on potential cyberthreats.

Last week, Obama signaled in a statement he wants CISPA to include more privacy safeguards for individuals, but did not say if he would veto the bill should it reach his desk in its current form.

The version of CISPA up for consideration this week is identical to one that failed to reach Obama's desk in 2012, which included an amendment from Amash.

That amendment exempts information like individuals' tax returns and educational, medical and firearms sales records from being used by federal officials under CISPA.

Amash ultimately voted against that version of CISPA. Huizenga voted in favor.
