Washington (CNN) Sen. Kamala Harris came out against President Donald Trump's pick to lead the CIA, Gina Haspel, on Wednesday, telling CNN's Jake Tapper she plans to vote against the nomination.

"I intend to vote against her as the nominee," the California Democrat said on "The Lead with Jake Tapper." "I will not vote to confirm her as the next director of the CIA."

Harris said her decision to oppose Haspel's nomination is "not about the integrity of the men and women of that agency or its mission" but rather "about whether this particular person should head that agency." The senator said she is concerned that Haspel "is not the best signal to the workforce of that agency, to the American people or to our neighbors around the globe."

Earlier on Wednesday, Haspel, a 33-year veteran of the agency who is currently serving as acting director, vowed not to restart the CIA's controversial detention and interrogation program during a confirmation hearing by the Senate Intelligence Committee.

However, Haspel declined to answer "yes or no" during a tense exchange with Harris when the senator asked whether the use of interrogation tactics that critics say amount to torture was immoral.
