"I'm ready for Clinton because she is the best person to take on the challenges that face our country, and she has more than enough qualifications, achievements and experience to do the job," Stabenow wrote in a CNN op-ed.
The Michigan Democrat noted that she and Clinton both arrived in the Senate at the same time, after the 2000 elections, and have known each other for more than 30 years. She went on to praise Clinton's work as secretary of state as well as her record on raising the minimum wage and ensuring quality, affordable health care.
"When America chooses its next president, we need someone who understands that people across this country are working hard and just want a fair shot to get ahead in life," Stabenow concluded. "I know that Clinton understands this because that's the America she has been fighting for all her life. That is why I am ready for Hillary Clinton -- and why America is, too."
Sens. Claire McCaskill (D-MO) and Tim Kaine (D-VA) previously announced their endorsement of Clinton and the Ready For Hillary super PAC unofficially backing her potential bid, although the former secretary of state has yet to decide whether to run for president.
