 On Friday we talked about a controversy surrounding the NSA, the US National Security Agency. A lot of this goes back to a man named Edward Snowden. He was a contractor who worked for the NSA. Earlier this year, he leaked information about secret NSA programs. Snowden fled to Russia to avoid US prosecution. The document's detail how the US intercepted and collected phone and email data of Americans. They've also accusations of spying on foreign leaders. White House leader said the surveillance activities are necessary to combat threats against the US and its allies. Lisa Monical is an adviser to President Obama on the issue of homeland security and counter terrorism. She says the president has ordered an review of government surveillance programs. Monical says: "We want to ensure we're collecting information because we need it and not just because we can." But meanwhile, some members of Congress, both Democrats and Republicans are speaking out against NSA programs. They are proposing a law to limit the amount of data that NSA can collect. This weekend, a protest outside the US Capital pushed for the same goal.
