The Trumpsters' line seems to be that Don Jr., Manafort and Kushner didn't do anything illegal. That remains to be seen, but is legality the only bar we expect our political leaders to clear? Trump Jr. has already lied repeatedly about this and, by his own admission (finally), acknowledged that he enthusiastically met with someone who he thought was an agent of the Russian government and who wanted to influence the outcome of US election as part of the Russian government's support of Trump. There is really no credible way to spin that as anything but reprehensible.
