Let's end where we began.

Why do we care so much about the first 100 days of a presidency?

Why did this term, the first 100 days, become a historical cliche?

We know there's nothing special about the number 100.

If humans that evolve to have different numbers of fingers on their hands, we might focus

on the first 64 or 128 days.

What we care about is the early days.

Enough of them that a president has had time to establish a track record, but few enough

that we're still clearly in the first chapter.

Setting a benchmark several weeks into a presidency, whatever number we use to demarcate

it, serves a helpful purpose.

It allows us to evaluate how well a new administration is functioning, after it's had

a chance to find its sea legs.

And whether it has established a foundation, it will serve it well for the coming years.

We began amid a flurry of executive actions, staffing changes, the transfer of Senate control

under democratic hands, and big ambitions for precariously narrow governing majority.

A lot has happened since then.

President Biden's big week so far and a big week to come.

Folks, have good news.

Everybody is able to rise up today to get the vaccine.

President Biden announcing a new goal on greenhouse gases.

We're going to begin with a big announcement.
