The NBC News host, who specializes in national security and the Pentagon, was talking about Turkish airstrikes being underway in northern Syria during a live broadcast when her son wandered onto set and interrupted her, grabbing her shoulder and microphone chord multiple times.
"Excuse me, my kids are here... live television", she said as NBC cut to a map of Syria and Turkey.
It's pretty hilarious - Kube sees little Ryan walking up on her monitor and has a moment of panic, but keeps it completely professional and continues delivering the news while trying to shoo her son away.More news: N.Y. Judge Blocks Trump Administration's Public Charge Rule

He then appeared at Kube's elbow, reaching up for her while saying, "Mommy", as she struggled to finish her sentence.
MSNBC didn't seem to mind though and tweeted a video of the incident, writing: "Sometimes unexpected breaking news happens while you're reporting breaking news".
"I couldn't love this more".
Watchers also praised Kube for handling the situation with warmth and grace. She has a master's degree from American University, lives by the beach with her three kids and husband and hopes to own a pig one day.
