President Donald Trump reportedly wants the U.S. to sell Fannie Mae and Freddie Mac stock in a quest to move mortgage finance firms from full federal control.

Some officials believe the offering could raise around $30 billion and value the combined firms at roughly $500 billion or more.

U.S. President Donald Trump's administration could kick off initial public offerings of Fannie Mae and Freddie Mac later this year, according to a senior administration official, marking a key milestone for the mortgage finance giants that have been under government control for years.
