Next week, CNN reports:
It is not surprising that Gingrich is suspending his campaign for the White House as he has all but acknowledged it is winding down and Romney is the presumptive GOP nominee.
"When he says he is transitioning, what he means is that he is trying to determine as a citizen how he will pro-actively help Mitt Romney become president and the Republican Party win back the Senate and help (House Speaker) John Boehner keep his majority in the House," said one of the sources, who spoke on the condition of anonymity.
Gingrich will reportedly drop out on May 1.
Meanwhile, taxpayers are shelling out $40,000 a day for his Secret Service protection.
