Simple majority to impeach (which they easily do, as you can see). Then:
"Third, the Senate tries the accused. In the case of the impeachment of a president, the Chief Justice of the United States presides over the proceedings. For the impeachment of any other official, the Constitution is silent on who shall preside, suggesting that this role falls to the Senate's usual presiding officer, the President of the Senate, who is also the Vice President of the United States. Conviction in the Senate requires the concurrence of a two-thirds supermajority of those present. The result of conviction is removal from office and/or disqualification from holding any federal office in the future."
Is impeachment 2/3rd majority or simple majority?

So if it falls after the 20th, it would be cameltoe, if you can impeach someone who isn't holding office, can you preimpeach someone?
Can't impeach him when he isn't holding office for sure. Or pre-impeach, I think.
