Joe Biden's driving a wedge between some of Andrew Jackson's descendants ... there's a split in the family over the new look in the Oval Office.
The rift stems from Biden's decision to remove a portrait of our 7th president from the Oval, replacing Jackson with a painting of Benjamin Franklin. It's a change from the layout during Donald Trump's time in the Oval.
Jackson's great, great, great-grandson, Andy Jackson, tells TMZ ... he's unhappy and thinks his great-great-grandpa has a rightful place near the resolute desk.
Andy, Barbara's cousin, says President Jackson should be remembered for his accomplishments -- defeating the British in the War of 1812 and increasing suffrage -- even if history doesn't look kindly on his cruel policies on Native Americans.
There's some common ground among Jackson's relatives, who descend from his adopted son Andrew Jackson II ... they both feel the decision was ultimately Biden's to make, and they respect it.
Here's a potential tiebreaker -- Andrew Jackson's Hermitage.
Howard Kittel, the President and CEO of Jackson's former plantation turned museum, tells TMZ ... he was disappointed to see the portrait taken down, but not surprised, given Jackson's ties to slavery.
There's also a Lincoln bust that was removed from the White House, but it wasn't Biden's doing. It got carried away in the final days of Trump's presidency.
