President Barack Obama has formally endorsed Hillary Clinton, but his closest ally does not approve of the Democratic one bit: The President’s wife Michelle Obama.

Surprisingly, Michelle Obama made no mention of Clinton’s “historic moment” for women during the entire White House United State of Women conference on Tuesday, which is an event to promote the power and advancement of women. In fact, the current FLOTUS has remained silent since the former first lady claimed the presidential candidacy for the Democratic party.

The First Lady participated an interview with Oprah Winfrey during the conference which focused heavily on the power of women – but Hillary Clinton was not discussed by First Lady Obama or Winfrey. Michelle Obama also delivered a speech at the conference – again, she made no mention of Clinton.

After President Obama endorsed Clinton in a web video last week, White House Press Secretary Josh Earnest asserted the first lady was “enthusiastic” about Clinton’s campaign and the video is a “joint endorsement.” However, this is not the case, since Michelle hasn’t expressed any true enthusiasm for Clinton due to old wounds.

A book published in April claims Michelle Obama has no love for Hillary Clinton as a result of bad blood during the 2008 primary campaign, when her husband was up against her. “The 2008 presidential campaign left deep and lasting scars on both the Clinton and the Obama camps, and they are still shockingly fresh,” wrote Kate Anderson Brower in her book First Women, the Grace and Power of America’s Modern First Ladies.
