It is absolutely credible -- is it not? -- that on the very day when then-President Obama imposed sanctions on Russia, Flynn -- acting entirely on his own, totally without the president-elect or vice-president-elect's knowledge or approval or direction -- called up the Russian ambassador and suggested (at a guess) that he not react, just hang in a few months till the new administration came in. Such a loose cannon would deserve to be fired; I can't imagine -- or can I? -- why he was allowed to resign.
