President Barack Obama faces a make-or-break week as he tries to seize control of three scandal story lines that could upend one of the top priorities of his second term, which is revising the nation's immigration laws, Bloomberg reported.


An Obama advisor said yesterday that the president won't cooperate in a "partisan fishing expedition" over who knew what about revelations that the Internal Revenue Service was applying added scrutiny to Tea Party-type groups seeking tax-exempt status.


Congressional committees also have begun probes into allegations that the Justice Department improperly collected phone records from the Associated Press in search of a government national-security leak and that the administration overlooked terrorist connections after the attack in Libya that killed four Americans.


The U.S. Senate is expected to begin debate on immigration law changes in coming weeks, which Obama's opponents are trying to undermine.


The Wall Street Journal reported that the White House's chief lawyer learned weeks ago that an audit of the IRS would likely show wrongdoing, a disclosure that has prompted debate as to whether the president should have been notified at that time.


Obama said last week that he learned about the controversy at the same time as the public, on May 10.
