The weak case for Trump's impeachment gets weaker if the whistleblower won't testify in person

The career government employee — excuse me, I mean “patriotic public servant” — who kicked off the impeachment proceedings is so confident in the substance of his complaint that he’s refusing to answer questions about it in public.

Lawyers for the so-called whistleblower said Sunday that he’s willing to testify in front of Congress but only in written form, meaning members could submit questions to his legal team and that his answers would come back in written form.
