Sen. Kyrsten Sinema (I-AZ) slammed President Joe Biden during an interview on Sunday for his repeated failure to secure the U.S.-Mexico border as the crisis is expected to intensify this week as Title 42 is set to end.

Sinema made the remarks during an interview with Margaret Brennan on CBS News’ “Face The Nation” while discussing the ongoing crisis at the border and new legislation that she has introduced that would act as a “band-aid” to address the issue.

Brennan highlighted actions that the Biden administration says they’ve taken to address the situation, including deploying a small number of troops to the border and creating a phone app for migrants.
