A bill that would establish new standards for cybersecurity in the United States was blocked Thursday by a Republican filibuster in the Senate, the Washington Post said.
The bill would have established optional standards for computer systems that oversee all of the United States' critical infrastructure, the Washington Post said.
Senators voted 52 to 46 in favor of the bill, but fell short of the two-thirds majority necessary to force a final vote, the Washington Post said. The bill had bipartisan support, but neither part could agree on proposed amendments to the legislation.
In an effort to win over detractors of the bill, Senator Joseph A. Lieberman made the standards outlined in the bill optional instead of mandatory as was originally written, the New York Times said.
According to the New York Times, the bill's opponents were led by Republican Senator John McCain of Arizona. McCain sided with businesses that opposed the legislation, saying that the restrictions outlined in the bill were too demanding and would place a financial strain on private companies.
The Obama administration strongly supported the bill, and President Obama himself wrote an op-ed piece in the Wall Street Journal backing the legislation, the Washington Post said.
According to the Washington Post, the bill will likely be voted on again in the fall.
