Hillary Clinton to announce her VP pic this Friday

This could be tactical way of diverting some media attention away from the Republican Convention and Donald Trump and towards Hillary Clinton and her campaign but then again Hillary has to make a choice before the start of next week before the Democratic Convention on 25th of this Month.
Here is more about this speculation from the Hill.

A Hillary Clinton campaign aide appeared to confirm on Tuesday that the presumptive Democratic presidential nominee plans to announce her running mate on Friday.

During an interview with CNN, Karen Finney was asked whether the announcement would occur Friday.
“I expect that’s about right,” she said, refusing to give any hints about who the choice might be.

It has been known for some time Hillary will be choosing from her short list but the most likely choice will be either Labor secretary Top Perez or Sen. Tim Kaine from Virginia.
