“The Democrats are using their power to push an alarmist and false narrative that there is a problem accessing contraception,” said Louisiana Sen. Bill Cassidy, the top Republican on the Senate Health, Labor, Education and Pensions Committee.
If he really meant this, there'd be no problem passing a bill to protect contraception access. If there's already no problem getting it, and you're not intending to prevent people from getting it, a bill protecting access is at worst window dressing and harms no one.
I can only conclude they are intending to find further ways to prevent people from getting contraception, and don't want this bill to get in their way.
