He's right. They should recuse themselves, or be barred from voting.
So, Senators like Jerry Nadler or Kamala Harris (ex-Senator but still has a vote) should be excluded?
How can trump get a fair trial in his 2nd impeachment trial??
Did they claim that the election was "stolen"? Did they whine incessantly about voter fraud?
What has that got to do with anything? Trump is ostensibly being tried for inciting insurrection. Harris did that by praising, supporting, and encouraging rioters against the government for months as an example.
Except that she did not.
