Help with ID?

Can anyone help me out on these volunteers? Noxious weeds or diamonds in the rough? I'm located in the Portland OR area.
Two pictures of this one:

This is some sort of shrub. The "leaf" encircling the stem might help with ID.

Shrub or tree-to-be?

This is about knee high. No flowers yet.

Appreciate any ideas.

I think you are correct on the Horseweed. Appears to be a native ground cover, so I guess it can stay. Thanks so much for your help on that mystery.

#1 Euphorbia lathyrus, the so-called "Gopher Purge". Keep it.
#2 Choke cherry, Prunus virginiana. Yank it out!
#3 Weedy Apiaceae. Yank it out.
#4 Erigeron canadensis (syn. Conyza canadensis). Yank it out.

On second thought, because of the paired leaves, #3 might be Sambucus canadensis, the Elderberry. You might want to keep it to see what develops.
