Faced with the choice between changing one’s mind and proving that there is no need to do so, almost everyone gets busy on the proof.

In the past, human progress had to come at the cost of the environment. If we wanted energy, we had to burn wood or we had to burn fossil fuels. If we wanted to grow more food, we had to expand farmland, often at the cost of forests. But technology and innovation means we're very quickly decoupling these impacts, such that this conflict is no longer true.

The hour has come for a new generation to lead the Democratic Congress that I so deeply respect.

There is nothing that's off limits. If people think something is off limits, I make it my business to go make a joke about it; that's my job.

Is there anyone out there? Or am I all alone? It wouldn’t make a difference; still, I don’t wanna know.

If you don't know what you're living for, you haven't yet lived.

There’s an interesting trend that occurs in times of mounting pressure and high uncertainty, which is that it’s a natural human tendency to seek out people that agree with us, that are similar to us because it’s a source of comfort in a world that’s so rapidly changing.

Voting whether or not to remove a sitting President has been a truly difficult decision, and after listening to the arguments presented by both sides, I have reached my conclusion reluctantly. For the reasons above I must vote yes on the articles of impeachment. I take no pleasure in these votes, and am saddened this is the legacy we leave our children and grandchildren. I have always wanted this President, and every President to succeed, but I deeply love our country and must do what I think is best for the nation.

Good leaders are always at the ready, but not always at the front.
