On July 10, Bush has sign into law the FISA Amendment Act. The law allows the government to spy on emails, phone calls, web surfing, and other communications if they are conducted by a person communicating with someone outside of the country. The Law also includes immunity to telecommunication companies who participated in an illegal spying by the government. An older version past by the House was threatened to be veto by President Bush for not including this immunity.
The ACLU has issued a statement calling the law unconstitutional, and other has pointed that this law is an assault on fundamental rights such as the first and fourth amendment.

Numerous democrats have voted for the bill, among them Nancy Pelosi and Barack Obama. Obama, although promising to oppose the bill if it guaranteed immunity to the telecommunication companies, has voted for the bill. Obama has justify this by stating that the government should have the ability to defend the American people from terror attacks and that the newer version of the FISA bill allows a secret court, not the president, the right to decide who can be spied on.
