Michael Steele tore into the GOP senators who on Thursday took an oath to serve as honest jurors in the impeachment trial of Donald Trump despite previously claiming they dont care about the evidence against the president in the Ukraine scandal .

Dont stand in the chamber today and take the oath, Steele, the former chair of the Republican National Committee, said in an interview with MSNBC s Brian Williams and Nicolle Wallace .

Continued Steele:

Take your behind out of the chamber when its time to swear in, because you will be lying to the American people. Because youve already told us you plan not to be an honest juror. So, this is almost a joke in the sense that you have some of these senators walking into this room, standing in front of the country, standing in front of the chief justice of the United States, raising their damn hand to swear an oath that they know theyre not going to defend nor uphold.

Steele, the RNCs chair from 2009 to 2011, said it would signal to the American people that the rule of law doesnt matter, at least for some.

It would matter for you, said Steele, who has become a frequent Trump critic. Dont try that when you get called for jury duty the next time. Dont try that when youre sitting in front of a judge under indictment because the rules, when applied to you, will come crashing down around your head.

Thats the responsibility at this moment that I think a lot of these members are going to let slip by, Steele added, describing the actions of the Republican senators as disgusting and un-American.

They should be embarrassed to stand there and take the oath when theyve already told us they plan to lie when they do so, he concluded.
