On May 26, 2010, legal blogger Ed Whelan reported that President Obama has placed Halligan on "the inside track" to be nominated to one of two vacancies on the United States Court of Appeals for the District of Columbia Circuit. Then, in July 2010, the Blog of Legal Times reported that two unidentified lawyers said agents with the Federal Bureau of Investigation had interviewed them regarding Halligan, which is standard for federal judicial nominees and often is precursor to a nomination. On September 29, 2010, Obama nominated Halligan to replace John G. Roberts.
Halligan was renominated on June 11, 2012. Two more attempts to gain cloture on her confirmation failed, and on August 3, 2012 her nomination was again returned to the White House. She was renominated on September 19, 2012. Her nomination was again returned to the President on On January 2, 2013, due to the sine die adjournment of the Senate.
On January 3, 2013, she was renominated to the same office. Her nomination was reported by the Senate Judiciary Committee on February 14, 2013, initially in a 10-8 vote, strictly along party lines. However, Sen. Lindsey Graham later changed his vote to "pass," making the final committee vote 10-7.
On March 4, 2013, Senate Majority Leader Harry Reid again filed a motion to invoke cloture on Halligan's nomination. On March 6, 2013, cloture failed by a vote of 51 ayes to 41 nays. According to Senator Charles E. Grassley one objection by Republicans to the nominee were based on a legal theory she advanced while Solicitor General of New York that "gun manufacturers, wholesalers and retailers contributed to a ‘public nuisance’ of illegal handguns in the state."
On March 22, 2013, Halligan requested that Obama withdraw her nomination to the D.C. Circuit.....snip~
