“I certainly cannot in any way support President TrumpDonald John TrumpProtesters tear down statue of Christopher Columbus in Baltimore 'Independence Day' star Bill Pullman urges Americans to wear a 'freedom mask' in July 4 PSA Protesters burn American flag outside White House after Trump's July Fourth address MORE this year,” Powell said on CNN’s “State of the Union.”

Powell said he is “very close to Joe Biden,” noting that he has worked with the former vice president for four decades.

“He is now the candidate, and I’ll be voting for him,” Powell added.

Powell said Trump “has not been an effective president” and “lies all the time,” starting with his first day in office about the size of the crowd at his inauguration. 

“I didn't vote for him [in 2016]. The situation ... has gotten worse,” he said. “Every American citizen has to sit down and think through — don't listen to everybody out there. Don't read every newspaper. Use your common sense. Say, ‘Is this good for my country?’”

“Make America not just great but strong for all Americans, not just a couple,” Powell added.

Trump called Powell a "real stiff" in a tweet after the former general announced his endorsement of Biden.

"Colin Powell, a real stiff who was very responsible for getting us into the disastrous Middle East Wars, just announced he will be voting for another stiff, Sleepy Joe Biden. Didn’t Powell say that Iraq had 'weapons of mass destruction?' They didn’t, but off we went to WAR!" Trump said.

Powell also served as the chairman of the Joint Chiefs of Staff under former Presidents George H.W. Bush and Clinton. 

Powell's statements come on the heels of a number of condemnations from high-profile current and former military officers on Trump's handling of nationwide protests over police brutality and racial inequality. Former Trump Defense Secretary James MattisJames Norman MattisTrump insulted UK's May, called Germany's Merkel 'stupid' in calls: report Mattis urges people to wear masks in PSA about 'nasty little virus' Dozens of GOP ex-national security officials to form group to back Biden: report MORE issued a blistering statement Wednesday, calling Trump the first president in his lifetime who is trying to divide Americans.

Powell said he agreed with the criticism. 

“We have a Constitution, and we have to follow that Constitution. And the president has drifted away from it,” Powell said. 

Powell said he didn’t write a statement, as Mattis did, in response to Trump’s actions because he made his point four years ago when Trump was a presidential candidate. 

“When I heard some of the things he was saying, it made it clear that I could not possibly vote for this individual,” Powell said. 

He said he was “deeply troubled by the way” Trump was “going around insulting everybody,” noting Trump’s attacks on a gold star mother and the late Sen.

“I agree with all my former colleagues,” he said on the criticism over Trump’s response to the protests. 

He said that many of the officials now making their voices heard were junior officers when he left the military 25 years ago and that he was “proud of them.”
