'American Idol' Finalist Jax: White House Gig is About Patriotism, Not Politics

EXCLUSIVE

Jax has a once-in-a-lifetime opportunity to perform at the White House on Independence Day, and nothing's going to stop her ... despite the inevitable backlash for hangin' with Donald Trump.

The Season 14 "American Idol" finalist tells TMZ she finds it sad people can't separate politics from patriotism because she has a lot of the latter ... and for good reasons.

For Jax, her upcoming performance is all about honoring her country and her family -- her younger bro is a Marine and her dad was a 9/11 first responder -- she says it's not at all about POTUS.

Jax will join fellow 'AI' alum Jonny Brenns and country music singer Sara Evans for a July 4 evening concert on the south lawn of the White House, with the Prez and First Lady Melania Trump in the crowd.
