I find it interesting that the Secretary of Labor is also an Acosta: Alexander Acosta.
I did some digging to see if there were some connection between Alexander and Jim.
All I found is that Alexander is a native of Miami, a decedent of Cuban immigrants.
Jim is a native of Virginia, his father is also a Cuban immigrant, and he has an Aunt in Miami.
Most of this info came from Wiki.
I haven't yet been able to find a direct connection (cousins?) between the two.
Even if there is a familial connection, it doesn't necessarily mean that Jim, or even
Alexander, is/are (our/guy(s)). I just find the coincidence intriguing.
