First lady Melania Trump may be a fan of Supreme Court Justice Brett Kavanaugh but she won't be attending his ceremonial swearing-in Monday night at the White House.

She has a "longstanding prior commitment" she can't break, says her spokeswoman, Stephanie Grisham.

“The First Lady regrets that she will not be able to celebrate with the Kavanaugh family on such a special evening, but she has a longstanding prior commitment she was unable to change at the last minute,” Grisham said in a statement.

Significant? Probably not; after all, Trump praised Kavanaugh as "highly qualified" during a brief gaggle with reporters as she posed Saturday in front of the Sphinx and the Pyramids in Egypt during her just-completed tour of Africa.

She said she was happy that both Kavanaugh and his main accuser, Dr. Christine Blasey Ford, were heard during the bruising Supreme Court confirmation hearings for Kavanaugh, which ended with a U.S. Senate vote to confirm on the same day Trump spoke in Egypt.

"I’m glad Dr. Ford was heard, I’m glad Judge Kavanaugh was heard (and) that the FBI investigation was done, completed and that the Senate voted,” she said. When asked whether she believed Ford's allegations that Kavanaugh sexually assaulted her when they were in high school, Trump deflected.

“I will move on (from) that.”

But that likely won't stop critics on Twitter from continuing to read meaning into Trump's bland statements and enigmatic moves – or from using her to condemn President Donald Trump and his policies.
