Here’s my take...
Obama is now getting briefings on National issues. Maybe investigations of corrupt state governments came up - or was scheduled to come up. The FBI realized that Obama and Blago are buddies. So, he had to be nabbed before BHO would warn him. Blago seemed to know something was going on yesterday based on comments he made. Maybe he already was tipped off...
BHO was at the National Governors Meeting, so was Blago. They met - there is a picture of it online - just can’t find it.
Either way, good job FBI.
If he was tipped off, there wouldn't be any point in continuing the investigation. Fitz may have also decided to do it now before being fired. He is public enemy number 1 in Chicago. It will make it harder for Obama to toss him with a major corruption case pending..
Also, is it possible that having arrested Blago, the FBI has more leverage to roll him over against Hussein?
