Transcript for Biden calls FedEx mass shooting ‘national embarrassment’
Will, thank you. President Biden is responding calling mass shootings in the U.S. A national embarrassment. The flag at the white house again lowered to half staff to honor the victims, the third time since Biden took office. But tonight, the president is under mounting pressure to move on gun control. Here's ABC's white house correspondent Maryalice parks. Reporter: As gun violence surges, president Biden sounding increasingly frustrated. This has to end. It's a national embarrassment. Reporter: But Biden also sounding defensive when asked if he should be prioritizing passing new gun laws. I've never not prioritized this. No one has worked harder to deal with violence used by individuals using weapons than I have. Reporter: On the campaign trail, Biden promised to take the issue head on. My first day of office, I'm going to send a bill to the congress repealing the liability protection for gun manufacturers, closing the background check loopholes and waiting period. Reporter: But on day one of the Biden administration, there was no big push for gun control. And with 29 mass shootings so far this month, the white house now saying it's on congressional Republicans to come to the bargaining table. What's next? Give us some preview of what other executive actions you guys are considering. Because otherwise it's just passing the buck to capitol hill. I think it's hardly that. All of you should pressure Republicans in the senate and ask them why they are opposing universal background checks when the vast majority of the American public supports it. Maryalice parks joins us from the white house now. Maryalice, president Biden has taken some executive action on guns, but advocates say it's not enough. Reporter: Yeah, whit, the president has taken some initial steps, including targeting so-called ghost guns that can be assembled at home. But you're right, advocates say he could do more right now on his own, including cracking down on gun dealers who have violations, limiting some private sales, and perhaps appointing a director to coordinate the federal response to gun violence. Whit? Maryalice, thank you.
