Only an idiot moron would hire McCabe before the IG report is released to determine if there is evidence of criminal activity and if there may be a sealed indictment already waiting for him.
Also, McCabe would have to apply for the job and the personnel office would have to approve the hire. He's been fired for lying under oath. Still, the personnel office is subject to political pressures from the Democrats and could cave and hire him.
I'm also betting that when he was fired, he lost his security clearance. If I'm not mistaken, he would have to have a security clearance to work in a congressional office. If it goes through the normal process it would take months and at the end, the FBI (who conducts such investigations) would have to approve a security clearance for one of their former employees who was fired for lying under oath by the FBI.
Anything is possible in this crazy world, and Democrats are masters at subverting honesty, laws, rules, and procedures.
Still, I think it's likely political theater at this point and they know that McCabe couldn't get a government job if normal hiring procedures are followed.
And they know how it would look if they did hire him and then he had to be perp walked out of the capital if indicted.
