Meanwhile:

The IRS official in charge of the division accused of improperly targeting conservative groups will invoke her Fifth Amendment rights against compelled self-incrimination at a committee hearing Wednesday, a sign of concern that the political controversy is heading into the criminal arena.

That is, she will refuse to answer questions on the grounds that her answers might tend to incriminate her. A jury is not supposed to take pleading the fifth into account in reaching a verdict during a trial. We, on the other hand, are not on a jury and this is not a trial so we are well within our rights to draw an inference that there is criminality involved. And no doubt there is. The question now is whether the Republicans (and media) will go all out or go quiet.
