Obama deported more illegal immigrants than all previous administrations

[snopes]

Comment: I heard someone on the radio two days ago commenting on Obama's
newly signed whatever it was regarding not deporting illegal immigrants
who were brought to the US as children. This person was some kind of
analyst for some organization, and made the statement that the number of
illegal immigrants who have been officially deported during Obama's
presidency is greater than were deported during ALL the previous us
presidents' terms COMBINED. I'd like to know if this is true, and what the
source of that information is.
