Marco Rubio to Teach Part-time in Fla.

U.S. Sen. Marco Rubio will co-teach four classes about politics at Florida International University when the Senate is not in session.

His spokesman says the senator will co-teach four classes on Mondays and Fridays, along with two other FIU professors. He began teaching in May.

Rubio will earn $24,000 a year, under the limit senators are allowed for outside work.

Rubio taught a similar course part-time from 2008 to 2010, for which he earned $69,000 a year. He faced some criticism at the time for the salary, as the school faced a budget shortfall and the job had not been publicly advertised.

Rubio delivered FIU's commencement speech on Friday.
