Barack Obama: “And I think that's a testimony to the President's leadership on this front.”

Because if this becomes the new normal, there’s no reason to believe it will stop with her — or that future presidents, in either party, won’t do the same.

It is a decision about how do we face and embrace this finite amount of time we have on the planet.

The fact that any president, or any administration, is willing to engage in such transparent efforts to intimidate someone should outrage all Americans, regardless of how they feel about Congresswoman Omar’s political views.
