U.S. President Barack Obama is fully committed to pushing for Congress to ratify the Trans-Pacific Partnership (TPP) deal despite anti-trade sentiment gaining steam on the presidential election campaign trail, National Security Adviser Susan Rice said Wednesday.

Voter anxiety and anger over international trade and the 12-nation Pacific trade pact have helped propel the campaign of Donald Trump, the Republican front-runner, as well as Sen. Bernie Sanders, who is running against Hillary Clinton for the Democratic nomination.

"The president remains fully committed to working to achieve ratification on the U.S. side and encouraging all of our TPP partners to move through their domestic processes to do the same," Rice told Reuters in an interview Wednesday.
