The Note: Pressure building on Trump to act on guns

— -- The TAKE with Rick Klein

President Donald Trump is vowing to “move past clichés and tired debates” surrounding guns. With that, he kicks off …. a “listening session” at the White House.

When Trump convenes stakeholders and victims of gun violence today, the pressure will be building for action by a president who claims to like to act.

Signs abound suggesting that skepticism is warranted. The president spent part of his weekend raging at the FBI. Ugly corners of the internet are maligning students motivated to act by what they witnessed in Florida.

Yes, “bump stocks” are now on their way to possibly being banned, but it took another massacre after Las Vegas to get that moving. Meanwhile, lawmakers in Florida quickly dispatched an assault-weapons ban, with students from Marjory Stoneman Douglas High School watching from the gallery.

There’s a lesson there for students, and for the broader public. Other moments have felt different, too — until they weren’t any longer.

The RUNDOWN with MaryAlice Parks

In Texas, one congressional candidate has had enough. Laura Moser, a Democrat running in the Houston area, launched a new television ad in the red state calling for action on gun control.

“Only a tiny fraction of members of Congress are mothers of school-aged children,” Moser says in the ad, over footage of her with her young daughter. “Do you think this would still be happening if we had more?”

Across the country, candidates of all stripes are getting questions about gun violence this week. Florida politicians, in particular, are feeling the heat.

And while some Democrats have used the moment to reiterate ideas about stricter gun-safety measures and draw contrasts with their GOP opponents, the new messaging push from Moser seems to be more of an anomaly than a trend in districts Democrats hope to flip.

In Tennessee, the Democrat running for governor, was vague in an interview this week about the need for common-sense gun ownership and “making the gun background check process more rigorous as it relates to mental illness.”

Conor Lamb, the Democrat running in a special congressional election in a redder part of Pennsylvania next month, had previously positioned himself as pro-gun. He met with the local Moms Demand Action group in the aftermath of the Florida shooting, but has continued to be lukewarm about supporting new gun laws.

In Colorado, one Democrat called on the incumbent Republican to return NRA money, but in Washington state's 8th Congressional District, where the Republican frontrunner is also a big-time NRA beneficiary, Democrats were tamer, calling for universal background checks, the closing of gun-sale loopholes and funding for a select committee to study the issue in Congress.

The TIP with Meridith McGraw

One of the three main Republican candidates in the very heated — and very close — West Virginia primary race was endorsed Tuesday by Wisconsin governor Scott Walker.

West Virginia Attorney General Patrick Morrisey said Walker's endorsement "will excite the many conservatives across West Virginia and the nation who have rallied to our campaign."

In a statement, Walker praised Morrisey, who is running neck-and-neck with Republican Rep. Evan Jenkins in a nasty, mudslinging primary to take on Democratic Sen. Joe Manchin.

"Attorney General Morrisey's strong, conservative record is exactly what West Virginia needs in its next senator," Walker said. "Patrick has fought for West Virginians while defending the rule of law, and he is ready to keep fighting for them as a champion of conservative reform in Washington, D.C."

This is Morrisey's first major endorsement of the primary, but it's not clear how many conservatives in West Virginia will be swayed by Walker's stamp of approval.
