Extending an olive branch to GOP senators, Texas Sen. Ted Cruz is privately making it clear he won’t engage in the Senate Conservatives Fund’s hardball tactics to defeat his colleagues in their primary races.

At a closed-door lunch meeting of Senate Republicans Wednesday, the freshman conservative told his colleagues that he would not intervene in their 2014 primary fights or fundraise for the controversial outside group. Cruz added that the SCF’s decision to try to defeat sitting GOP senators in their primaries was its alone, according to several people familiar with the session.

According to one source familiar with the meeting in the Senate’s Mansfield Room, Cruz noted that Republican Sens. Mike Lee of Utah and Rand Paul of Kentucky wouldn’t fundraise for the group and promised that his image would be removed from its materials. Senate Minority Leader Mitch McConnell (R-Ky.) told Cruz that Paul took such an action six months ago, but he thanked the Texas conservative for doing so. Other GOP senators also thanked Cruz, sources say.
