Your source does not suggest that Obama was aware of the problem, nor does it suggest he created the policy that caused it.So you didn't read the LINK.
Can you provide proof that Trump was aware of the problem or created the policy that leads to the problem?
If you want to blame Trump that is what you need to do.
I can provide proof on both, they were or are the POTUS
Libs were quite as Christmas Mice when it was Bush & Obobo and only SOME so apparently libs think if you rob a bank and only take SOME money it's not a crime???????
Don't get mad get factual if you want to make a point.
