What did Donald Trump do today?

He contradicted himself in a single tweet.

This morning, seemingly apropos of nothing, Trump tweeted this:

Why did the Obama Administration start an investigation into the Trump Campaign (with zero proof of wrongdoing) long before the Election in November? Wanted to discredit so Crooked H would win. Unprecedented. Bigger than Watergate! Plus, Obama did NOTHING about Russian meddling.

Setting aside the fact that investigations seldom start with "proof of wrongdoing," there's a slight problem here. Either the FBI and various intelligence agencies investigated the Trump campaign's connections to Russia, or the Obama administration "did NOTHING about Russian meddling." Both cannot be true.

Trump has steadfastly refused to implement legally mandated sanctions against Russia for its "meddling." It was also reported yesterday that Trump's State Department, which was allocated $120 million by Congress to combat further Russian election sabotage, has refused to spend any of it.

So what?

• Accusing other people of failing to do what you are failing to do is hypocrisy.

• Even if a president thinks his predecessor left him a problem, he still has to actually try to solve it.
