Lauren Blair Bianchi, the communications director for Republican Texas Senator Ted Cruz since April 2019, has resigned, reportedly because she was increasingly uncomfortable with Cruz’s tactics to undermine the 2020 Presidential election, HuffPost reports.

While Bianchi released a statement thanking Cruz for the opportunity to serve the government and wishing him well, a source close to Bianchi told HuffPost she left because she was “not comfortable” with the rhetoric Cruz was using.

“Since the election it was becoming clear things were moving in a direction that she was not comfortable with and that culminated with last week’s tragedy in the Capitol,” the source told HuffPost. “Given that every member of Congress deserves to have a staff aligned with and supportive of their vision, and coupled with the start of the new Congress, she felt it was an appropriate time to step aside.”

Cruz and Republican Missouri Senator Josh Hawley has been spotlighted for incendiary rhetoric that fanned the flames of violence and anger, leading to the coup attempt at the Capitol last Wednesday in which five people died.

Cruz and Hawley have been blamed for falsely claiming Congress or the Vice President had the Constitutional power to undermine the states’ slates of Electoral College electors to re-install Donald Trump in the Oval Office after he lost both the Electoral College vote and the popular vote.
