White House Reportedly Bracing for Staff Exodus

A number of aides expected to leave in coming months

A number of key aides are expected to leave the White House in the coming months as President Obama tries to build momentum after a tumultuous 2013 that left him with few significant achievements.

Departures of longtime and trusted West Wing aides will force Obama to go outside his comfort zone in seeking advisers.

Strategists say that could be a struggle for the president, who they say has not done well in reaching outside his bubble for help and advice.

It will be critical in 2014 for the president, who is focused on making sure his party does not lose its majority in the Senate.
