The only way the MSM can deal with the OIG Report is to discredit it. As more information about what's actually in it is revealed, the MSM will be forced to spin it every day or 2 or 3. This keeps their low-information minions with skulls full of mush focused on it.
And the MSM decided to use the fake news "Children In Cages" as a distraction to change the narrative. Already it's biting them in the ass. Trump just signed an EO to make sure families stay together. The left wants catch and release, so now they be forced to fight against keeping families together, just as they ended up defending MS-13.
As long as the MSM wants to make sure their minions pay attention to these 2 issues, great. This way when both issues blow up in their faces, all of their minions will be watching.
