President Donald Trump revealed new details Friday about first lady Melania Trump’s medical procedure last month, saying she had a “big operation” and couldn’t go to the G7 with him because of doctor’s orders.

“First lady’s great, right there,” Trump told reporters from the South Lawn before leaving for the meeting in Quebec, while pointing to the upper-floor windows of the White House.

“She wanted to go. Can’t fly for one month, the doctors say. She had a big operation, that was close to a 4-hour operation. And she’s doing great,” Trump said about his wife, revealing more details than the White House had previously released.

The first lady checked in to the Walter Reed Medical Center on May 14 and remained hospitalized for five days.

She had not been seen publicly for weeks until she appeared at a meeting the president held with FEMA officials on hurricane preparedness this week.

Her spokeswoman, Stephanie Grisham, said in a statement at the time that she had an “embolization procedure for a benign kidney condition.”

But Trump’s statement made it sound as if the procedure was far more serious than that.

In a statement after the president’s comments, Grisham stood by her earlier comments.

“The statement I put out on May 14 was correct. Mrs. Trump had a successful embolization procedure. She cannot travel internationally yet, and is doing great,” the statement said.
