We know who did it, but who asked them to?

Chuck Ross writes at The Daily Caller,

The core questions are: Who tasked Halper, a former University of Cambridge professor, with contacting Trump campaign advisers Carter Page, Sam Clovis, and George Papadopoulos? What did they tell Halper, and what did he, in turn, tell his FBI/CIA handlers? And how was that information used by government officials in their investigation of possible Russian meddling in the 2016 election? Was Halper a credible source?

Carter Page holds the key to many of those questions.

An energy consultant and former Naval officer, Page was the first Trump associate known to have made contact with Halper. He also stayed in touch with the 73-year-old the longest of any of the three Trump advisers — from July 2016 to Sept. 2017. The pair met multiple times, including at Cambridge and at Halper’s farm in Virginia.

...But it is now clear that Halper was collecting some information on Page. And there has been speculation that whatever information he collected was provided to the FBI for use in Foreign Intelligence Surveillance Act (FISA) warrants granted against Page.

...The first FISA warrant authorizing surveillance on Page was granted on Oct. 21, 2016. Three renewals were granted in January, April and June 2017. They expired in September 2017, the same month that Page and Halper fell out of contact. As has been widely noted, FISA renewals require additional evidence showing probable cause that a surveillance target is acting as an agent of a foreign power.
