us.states.lookup("Washington D.C.") doesn't return a result

Should return D.C. I tried with DC_STATEHOOD also, which didn't make a difference. Could a proxy "state" to D.C. be a solution?

also was not able to append DC information to list of states or territories after placing:
os.environ["DC_STATEHOOD"]="1"
before and after import of us in code
Additionally, manually setting the variable in the script:
DC_STATEHOOD=1
did not append it either
