WASHINGTON – Sen. Marco Rubio on Tuesday reported modest earnings outside of his official Senate salary, including $18,000 for teaching at Florida International University.

He filed his 2017 financial disclosure on Tuesday and for the second consecutive year, it does not include income from book sales (which Rubio used in part to pay off student loans).

Rubio earned at least $1 million for his 2012 memoir "An American Son."

He has several bank accounts and college savings plans, plus a 2015 mortgage between $500,001 and $1 million. His wife earned income from a consulting business, JDR Events, but Rubio was required to show that it was more than $1,000.

Rubio also disclosed several travel costs, including a flight paid for by Rep. Francis Rooney, R-Naples, for travel to Washington from Miami, and a flight to Key West via Dr. Claudio Miro, as well as a fishing trip with Dr. Alex Trujillo.

Here is Sen. Bill Nelson's disclosure.
