IF the Senate wants to open their f'n eyes and grow a SPINE, there is no question as to whether or not they should call Bolton and NEITHER BIDEN can shed ANY light on the Ukranian call. All the Bidens would do is DEFLECT from the issue. The American people are NOT stupid. The GOP is STUPID because they refuse to stand up to the asshole in the WH. Just remember what you condone now, u will have to condone FOREVER!
