Michelle Obama is still fighting the good fight when it comes to issues that matter to her.

Obama sat down with Sam Kass, the former White House chef and senior advisor for nutrition policy, in Washington, D.C., on Friday for the Partnership for a Healthier America summit to address childhood obesity. And she took aim at President Donald Trump's policies.

"This is where you really have to look at motives," she said. "You really have to stop and think, 'Why don't you want our kids to have good food at school? What is wrong with you and why is that a partisan issue?' Why would that be political? What is going on?"

Access to healthy school lunches was the former first lady's focus while in the White House, and Trump's administration has been rolling back those efforts.

The Obamas took some time for themselves after Trump's inauguration in January, inking book deals, vacationing and just generally living their best lives.

But they're back and they're not going anywhere.

"We're not gone, we're just breathing, y'all. Let us breathe," Obama insisted, per People magazine. "We've got to get our new lives set up."

"When you hear me getting riled up in this chair, it's not politics, it's parenting that's really moving me," she said, adding that everyone needs to "put aside our politics ... to not be cynical ... to not give up."

"You've got me as a partner as long as I can be of use," she said. "So the question for you is, where do you want me? Just let me know and I'll be here."

Glad to be back at the #PHASummit. No one should play politics with our kids' health. We owe them. Let's make our voices heard. pic.twitter.com/g2ZDbwZk5u
