The inspector general is also scrutinizing another early source of information for the Russia investigation, the people said: Mr. Horowitz’s investigators have been asking questions about the role of Stefan A. Halper, another F.B.I. informant, and his prior work for the bureau. Agents involved in the Russia investigation asked Mr. Halper, an American academic who teaches in Britain, to gather information on Mr. Page and George Papadopoulos, another former Trump campaign foreign policy adviser.

Unfortunately, the Times is again late in reporting. In May of 2018 TGP reported that Halper was identified as the spy working for the Obama Administration to entrap candidate Trump team members –

It has been widely reported that the Obama administration had a spy working inside the Trump campaign. As previously reported internet sleuths have determined who the FBI spy was inside the Trump campaign. Jeff Carlson at theMarketswork on Thursday put together a piece where he places an individual by the name of Stefan Halper as a potential FBI spy into the Trump campaign. (Note that some believe that Obama may have had more than one spy on the Trump campaign).

The Mainstream media is finally and reluctantly reporting what we have been reporting for at least a year. Their credibility is gone.
