Inquiring minds want to know.

and could that render the pardon unconstitutional?

The President’s authority to exercise power begins immediately upon being sworn into office and
continues until he is no longer the officeholder. By the same token, while congressional oversight
of the executive branch is continuous, some activities may take on special significance at the end
or beginning of an Administration. The disposition of government records (including presidential
records and vice presidential records), protections against “burrowing in” (which involves the
conversion of political appointees to career status in the civil service), the granting of pardons,
and the issuance of “midnight rules” are four activities associated largely with the outgoing
President’s Administration. The incumbent President may also submit a budget to Congress, or he
may defer to his successor on this matter. Continuing this transition process, the first actions of a
new President generally focus on establishing the priorities and leadership of the Administration.
These can include executive orders, appointments to positions that require Senate confirmation as
well as those that do not, and efforts to influence the pace and substance of agency rulemaking.

May things go well for you
May they not go badly
May you reap in life
Whatever good you sow

May things go well for you
May they not go badly
May time leave you
Where you must stay

... you wanted to be universal
eclipsing a thousand dreams
May God protect you
in your cell of loneliness

I'm leaving to plant my fields
or to the edge of the tides
I hope all goes well for you
I'm leaving and you will stay

I'l leaving to live
in peace
without pause but in no rush

I hope all goes fabulously for you
I don't expect your visit
So don't come... I won't be here for you
...I won't be here for you.

Health, love, and fortune
I have everything in order
Health to see, Love to be,
Fortune to forget your name

I leave and take the moon with me
to where the sun does not set
He keeps me warm in Winter
and the moon lights my nights.

... you wanted to be universal
eclipsing a thousand dreams
May God protect you
in your cell of loneliness

Me neither.
