It's the first time in our nation's history two women are flanking an American president inside the House Chamber ... and Kamala and Nancy marked the occasion in style.

The mutual respect didn't stop with the iconic elbow bump, Kamala and Nancy also shook hands, even though they aren't supposed to get so close due to coronavirus protocols.

But, hey, this is a huge deal, so it's easy to understand how they could get caught up in the moment.

And, this is super interesting ... the two women who just made history tonight are not only both from Cali, they're both from the Bay Area. As Pelosi said today, there must be something in the water!

Get ready to see the elbow bump in history books one day, but in the meantime, we're sure it will get the meme and GIF treatment.
