Transportation Secretary Pete Buttigieg dismissed attacks from conservatives who have criticized him for taking paternity leave, saying on Friday that its shameful for people who claim to be pro-family to make such remarks.

Buttigieg weighed in on the discussion while speaking with MSNBC host Nicolle Wallace , who asked him what he thought about comments from Fox News personality Tucker Carlson , who disparaged Buttigiegs choice by saying, Paternity leave, they call it, trying to figure out how to breastfeed.

Buttigieg and his husband, Chasten, recently welcomed twins into their family. The transportation secretary is now on a six-week paternity leave.

Well, look, in his case, I guess he just doesnt understand the concept of bottle feeding, let alone the concept of paternity leave, he said.

But what is really strange is that, you know, this is from a side of the aisle that used to claim the mantle of being pro-family, Buttigieg added. What we have right now is an administration thats actually pro-family. And Im blessed to be able to experience that as an employee, being able to have the flexibility to take care of our newborn children, which is, by the way, work. Its a joyful work. Its wonderful work, but its its definitely work.

Buttigieg added that the crux of the criticism over his paternity leave that hes shirking job responsibilities while the U.S. deals with the massive global supply chain problems driving up prices is false.

I have been fortunate and privileged to be able to have this leave, but I have still been available 24/7 on issues that cant wait, issues that cant be delegated and major decisions, he said. And one of those issues that I have been involved with throughout is, of course, that of supply chains.

President Joe Biden s administration is working on passing legislation through Congress that would make 12 weeks of paid family and sick leave available to most workers. The U.S. is one of only a few countries that doesnt have such a policy in place.
