Do all States give death penalty for Treason?

No, not all states in the U.S. impose the death penalty for treason. While treason is a federal crime punishable by death under U.S. law, individual states have their own laws regarding treason and may not all prescribe the death penalty. Some states may have different penalties, such as imprisonment or life sentences. Additionally, some states have abolished the death penalty entirely, which would also apply to treason cases.
