The government wants to ignore the testimony because everybody else in government makes their fortunes in the same way. If the Bidens go down for it so should their republican counterparts...past and present. Don't hear much from McConnell on the matter do you? The Clintons? We would, literally, have to gut the government.
A very long time ago the people of this country decided that they were going to tolerate this corruption. It's going to be pretty hard to change course now.
