From libertarian Julian Sanchez of Cato Institute:
It hasn’t been built up by weeks of hype or a fevered social media campaign, but a letter from Sens. Chuck Grassley and Lindsey Graham—sent to the Justice Department in January, and released in declassified form this week—may be more significant than the now-infamous #memo #released by Rep. Devin Nunes earlier this month.
The Grassley letter and the Nunes memo both deal with the same thing: The FBI’s surveillance of former Donald Trump adviser Carter Page under the Foreign Intelligence Surveillance Act, and the role of a controversial dossier on links between Trump and the Russian government compiled by former British spy Christopher Steele. But while the Nunes memo has largely been greeted with justified ridicule, the Grassley letter makes a more direct and serious case that the FISA warrant targeting Page may have been issued on insufficient grounds—while at the same time undermining key aspects of Nunes’ argument.
