At this point, Trump supporters have only two options left in defending this mess:
1. Scream "fake fake fake" - the concept that any information, no matter how objectively true, which is critical of or in disagreement with the policies persued by the dear leader is automatically false. Reinforced by the echo chamber of the right wing media which does not tolerate or consider dissent of any kind, this magical thinking allows conservatives to square the circle and live in a world in which Trump is a wise, noble patriot rather than a corrupt plutocrat in bed with America's enemies.
2. Whataboutism - a series of false equivalencies designed to change the subject. What about Hillary Clinton (not in government) and the benghazemail blah blah blah? What about Obama (not POTUS) and the "deep state" he somehow implanted in government to ruin Trump's presidency?
There is no limit to what they will swallow as long as they can ensure the 1% get a huge tax cut and sick people lose insurance.
