Former First Lady Michelle Obama said she is suffering from "low-grade depression" from coronavirus quarantine, racial strife in the United States and the "hypocrisy" of the Trump administration.

Obama made the remarks in the latest episode of "The Michelle Obama Podcast" released on Spotify on Wednesday.

"I'm waking up in the middle of the night because I'm worrying about something or there's a heaviness," the 56-year-old former First Lady said.

"I try to make sure I get a workout in, although there have been periods throughout this quarantine, where I just have felt too low," she said.

The internal watchdog looking into accusations against Secretary of State Mike Pompeo abruptly quit Wednesday, just months after his predecessor was fired.

The State Department's acting inspector general, Stephen Akard, is a longtime aide to Vice President Mike Pence and his installation in May had widely been seen as a way to keep a friendly figure in the role.

Akard informed colleagues that he is "returning to the private sector after years of public service," a State Department spokesperson said.

"We appreciate his dedication to the Department and to our country."

But Akard's departure comes just as his office finalizes a report on Pompeo's controversial decision to bypass Congress to sell $8.1 billion in arms to Saudi Arabia and other Arab allies.
