From National Review:

Chipman is an activist, but the ATF needs an administrator. Chipman would raise the temperature of the gun-control debate, when precisely the opposite is needed. Chipman has shown poor judgment — from engaging in racially tinged office politics to allowing himself to be used as an instrument of public relations by a Beijing-run propaganda program — and the ATF, of all federal agencies, has had more than enough of poor judgment over the years.
