The pair is circulating a letter among House Democrats urging Pelosi to call back the relevant panels to take up related legislation.

"In the wake of the El Paso shootings, it is clear that terrorists motivated by a common white supremacist ideology are committing deadly attacks against African-American, Jewish, Muslim, Hispanic and other non-white communities in the United States and around the world, and that they pose a clear and present danger to our national security," reads the letter, which has been signed by 48 members so far.

The letter campaign was first reported Tuesday by Vice News.

The lawmakers have an uphill battle in convincing the congressional leaders to return to Washington amid the long August recess.

McConnell has warned that he won't consider any gun bills that don't enjoy the support of President Trump Donald John TrumpSteele Dossier sub-source was subject of FBI counterintelligence probe Pelosi slams Trump executive order on pre-existing conditions: It 'isn't worth the paper it's signed on' Trump 'no longer angry' at Romney because of Supreme Court stance MORE and bipartisan leaders in both chambers.

And Pelosi, on a conference call with rank-and-file Democrats Monday, rejected calls by some of her troops for the House to return to Washington to take up tougher gun laws and legislation addressing white nationalism. She's putting the onus on McConnell to return this month to move the House-passed gun bills — including proposals to strengthen the background check system prior to firearm sales — and her allies fear that reconvening the House would step on that message.

“It is understandable that Members have many enthusiasms right now," a senior Democratic aide said Tuesday by email. "However, this letter distracts from the enormous inside and outside public push on Mitch McConnell to act."

The aide added that the legislation to fight white nationalism promoted in the Democrats' letter "hasn’t been marked up and the author isn’t on any of the committees of jurisdiction."

"Now is not the time for the individual self-promotion of members’ pet bills,” the aide said.

The divisions highlight the tensions — both between the parties and within them — as lawmakers scramble in search of the appropriate response to Saturday's shooting in an El Paso Walmart, which left 22 dead, and a second mass shooting in Dayton, Ohio, early Sunday morning, which led to at least nine more deaths.

The suspect in the El Paso shooting posted a manifesto online saying the attack was motivated by a "Hispanic invasion of Texas."

The suspect in the Dayton shooting was killed by police.

Escobar, who represents El Paso, and Malinowski pointed to several bills aimed at tackling domestic terrorism, including legislation providing more resources to the Justice and Homeland Security departments to fight the threat.

Pelosi, in a letter of her own sent to House Democrats on Monday, noted that Rep. Bennie Thompson Bennie Gordon ThompsonHouse panel pans ICE detention medical care, oversight Senate to hold nomination hearing for Wolf next week Hillicon Valley: FBI chief says Russia is trying to interfere in election to undermine Biden | Treasury Dept. sanctions Iranian government-backed hackers MORE (D-Miss.), chairman of the Homeland Security Committee, is holding "a series of hearings" on white nationalism and domestic terrorism, beginning next week.

A spokesman for the committee said those will consist of roundtables and meetings outside of Washington during the recess, while formal hearings will take place on Capitol Hill when Congress returns next month.

For the letter's supporters, that's not fast enough.

"We should take the threat posed by white supremacist terrorists as seriously as we rightly take the threat posed by terrorists groups based outside the United States," the authors wrote. "Let us approach that work with the urgency it demands."
