GOODWIN: Mueller’s testimony equals end of any Trump impeachment talk.

More likely, the 74-year old former FBI director was something of a figurehead for an investigation that was carried out by the team of zealots he ­assembled.

That is not an incidental issue. As Andy McCarthy at National Review has written, and as Trump has repeatedly charged, the prosecutors were ­primarily people who had donated to Hillary Clinton and other Democrats or who otherwise made known their support for her.

Perhaps Mueller’s detachment explains his failure to remedy these obvious conflicts of interest that undercut his credibility from the moment they became known.

Oddly, Mueller removed FBI agent Peter Strzok because his bias against Trump became public, but apparently had no concerns about public reports showing that chief prosecutor Andrew ­Weissman and others were in Clinton’s camp.

Mueller’s detachment may also explain the bizarre standard his team created, where Trump’s presumption of innocence was shredded because they could not find sufficient evidence to “exonerate” him. Several Republicans pointed out that prosecutors either file charges or don’t, but have never imposed the impossible standard of exoneration.

Those flaws are among many that undercut the report, including the fact that much of it reads as if it were written by Trump-hating reporters from the New York Times.

Birds of a feather.
