In a bombshell decision on the limits of executive power, a federal appeals court panel in Washington, D.C., has invalidated President Obama's recess appointments to the National Labor Relations Board.
Legal experts say the court's reasoning upends decades of conventional wisdom and deals a big victory to Senate Republicans in an era of congressional gridlock.
Sen. Saxby Chambliss, R-Ga., won't seek re-election next year, he announced Friday.
The conservative Capitol Hill veteran faced recent criticism from the right for seeking a bipartisan compromise on deficit issues, and for being among the first high-level Republicans to question fidelity to Grover Norquist's no-new-taxes pledge after the November elections.
Those stances had raised speculation about a possible Tea Party-backed GOP primary challenge next year, when Chambliss would have been seeking a third six-year term.
