I can think of no legal grounds for @AmbJohnBolton to say he’d testify if (GOP controlled) Senate issues him a subpoena — but not testify when (Dem. controlled) House would.

Nor are there legitimate grounds for this show of disrespect to the American people who want answers. https://t.co/VI91kAhSOX
