Republican Jeb Bush on Wednesday bashed Democratic 2016 presidential contender Hillary Rodham Clinton for voicing reservations about overseas trade talks, a rare issue on which the White House enjoys support from Republicans, with many Democrats opposed.

Bush, the former Florida governor who is also expected to jump into the presidential race, said Clinton backed foreign trade agreements as secretary of state but has grown reticent now that she is seeking the Democratic nomination.

The U.S. Congress is debating whether to give President Barack Obama fast-track authority to negotiate deals such as the 12-nation Trans-Pacific Partnership. The White House says the TPP would open up new markets to U.S. exports and help businesses compete abroad.
