The head of a left-wing “watchdog” behind the Colorado Supreme Court’s ruling disqualifying former President Donald Trump from the state’s 2024 primary election ballot hobnobbed at the Biden White House last year, records show.

The U.S. Supreme Court agreed last week to hear the major case, which will be argued on Feb. 8. That case stemmed from a September lawsuit in Colorado filed by Citizens for Responsibility and Ethics in Washington, a Washington, D.C.-based charity that alleged Trump incited the Jan. 6 Capitol riot. Meanwhile, CREW President and CEO Noah Bookbinder has been afforded the opportunity to frequent the White House since President Joe Biden took office, according to White House visitor logs.
