A friend of mine had a pet pit bull who stepped on an ants' nest and got stung. He then proceeded to bite and claw at the nest until the stings either killed or incapacitated him. Donald Trump seems a lot like that. It's no surprise that he's now being investigated for obstruction of justice. Whatever real or imaginary crimes prompted the deceptions of Flynn et. al., Trump's ham-handed attempts to quash the investigations have now put him squarely in the prosecutorial sights. Many have suggested that he wouldn't have taken such a chance unless he had something big to hide. I'm not so sure. It's possible that his aggressive instincts just lead him from one dumb choice to another.
Personally, I hope that's not true. I'd like to think that he had a good reason, however evil, for putting the country through all this.
