Trump, Russia and Sanctions

Although Russia's unprecedented and dangerous meddling in the US election has been proven to the satisfaction of most open-minded Americans, Trump continues to express doubt and claims to be awaiting the findings of his own investigative team (probably the same team that looked into Obama's citizenship and "found things they can't believe").
While many suggest that Trump's reluctance to confront Russian misconduct is driven by his economic entanglement with Kremlin figures, I believe his principal motivation is his egotistical concern that his election may be seen as having been aided (and tainted) by Russian hacking thus, once again, putting petulant pride before national interest.
Most Republicans, true to form, are attempting to divert attention from Trump's unseemly stance by attacking President Obama, accusing him of imposing weak sanctions after waiting too long to act.
