"Allahpundit" is or is close to being a Never-Trumper. Agree or disagree with him, that is the bias he brings to matters Trump.
With that context, I think Trump's briefings inform the American people about events and progress the MSM are spiking. And Trump is letting the MSM go steroidal-beclown-mode in their "questions". So no, I think the daily briefings help Trump and the American people.
