Plant in question is in Southern MD. The small growing one is exactly like that of the tall tree growing next to it. Tree is about 18ft high. Is this a tree that should be taken cared of or chopped down? Thank you.

Thank you all, I'll consider this one solved!
I think stone nailed the ID. It sure looks like Black Locust (Robinia pseudoacacia) I don't think it's considered invasive here in the U.S. but I'm not sure. It's a gorgeous tree so if it's not considered a pest plant, I wouldn't chop it down.
