Mulberry.

That was my first guess. I may try and transfer them to my garden and try and keep them pruned to bush size.

White mulberry is a frequently seen weed tree in some areas - that gets asked about repeatedly due to it popping up all over, having polymorphic leaves particularly when young.

i would not waste my time moving it ... if you spend a little time.. you ought to find it elsewhere in your garden ... and it would be easier than diggin it out of a driveway

good luck on trying to make a large tree into a small shrub ...

Weed tree. You can do much better than trying to keep this. Now, maybe if you live in zone 3, this might be prized tree. Not sure.
