Fox News: Eight Republican senators and an independent group that supports tighter limits on immigration are warning that the Obama administration is drafting a plan to "unilaterally" issue blanket amnesty for millions of illegal immigrants as it struggles to win support in Congress for an overhaul of immigration laws. The senators who wrote the White House on Monday say they are concerned that the administration is readying a "Plan B" in case a comprehensive reform bill cannot win enough support to clear Congress.
