Former first lady Michelle Obama on Tuesday congratulated Valerie Jarrett, a top adviser to then-President Obama, on her new book, sharing a throwback photo of the two women together.

“Valerie was one of my earliest, and best, role models for how to be a confident woman and mother in the workplace,” Michelle Obama wrote on Twitter, along with an undated photo.

Jarrett responded by saying one of her favorite chapters in her new book, “Finding My Voice: My Journey to the West Wing and the Path Forward,” is about meeting the former first lady.

“Her friendship has improved my life every single day since we first met in 1991,” Jarrett wrote on Twitter.

One of my favorite chapters in #FindingMyVoice is “Best Hire Ever” and it is all about meeting @MichelleObama. Her friendship has improved my life every single day since we first met in 1991. https://t.co/lE3xgtaezj

Barack Obama also congratulated Jarrett on Twitter, calling her one of his “oldest friends and advisors.”

Valerie is one of my oldest friends and advisors – she was by my side when I first decided to run for office and for every major moment of the presidency. @ValerieJarrett‘s voice has often inspired me and I know “Finding My Voice” will inspire others to lift their voices, too. pic.twitter.com/nWTBDByMoz

The former Obama adviser reportedly isn’t entirely complimentary about his White House, writing about the “macho atmosphere” and how she confronted the president about how women in his administration felt intimidated, according to Axios.

{mosads}Jarrett wrote that she told Obama that women “rarely talk” in meetings, adding that “when you aren’t there to ask their opinion, they are becoming increasingly mute.”

He reportedly met with female White House staffers for several hours to listen to their concerns and suggestions on how to address the problem.

“He invited over a dozen of the senior women for dinner at the White House to discuss what was going on,” Jarrett reportedly wrote in the book. “He gave us his undivided attention for two and a half hours.”
