Former Secretary of State Hillary Clinton used her tribute to the late Sen. Dianne Feinstein (D-Calif.), who died last week at age 90 , to warn people that they really should take former President Donald Trump at his word.

We should believe him when he tells us what hell do next, Clinton cautioned about her 2016 election rival in an opinion piece for The Washington Post published Monday, noting how Trump has vowed to gut checks on executive power, weaponize the Justice Department to pursue political opponents and more if he wins back the White House in 2024.

Clinton recalled Feinsteins comment , after she exposed CIA abuses post-9/11, that: History will judge us by our commitment to a just society governed by law and the willingness to face an ugly truth and say never again.

Those are words we should remember as we face the challenges ahead, said Clinton. Dianne has left the national scene at another moment of political violence and threats to the rule of law. So, we must again face ugly truths and do what is right.

Diannes journey has ended, but the fights of her life are far from over, she concluded.
