The Obamas are "Becoming" a billion-dollar brand

Forbes estimated the couple made $20.5 million in salaries and book royalties between 2005 — when Obama became a federal senator and they first arrived in Washington — and 2016. They are now worth more than $135 million.

And that figure does not include the cash they are raking in for public speaking.

In October 2017, Michelle Obama was a keynote speaker at the Pennsylvania Conference for Women, a non-profit that promotes education and networking.

Obama did an on-stage interview with Hollywood producer and writer Shonda Rhimes in Philadelphia for an audience of 12,000.

The New York-based Harry Walker Agency Inc., which books both Obamas for speaking gigs, billed the Pennsylvania Conference for Women $225,000 in 2017, according to the non-profit’s most recent tax filings.
