A group linked to former President Barack Obama is targeting 34 vulnerable House Republicans in districts where President Donald Trump did poorly in 2016, McClatchy newspapers reported.

Organizing for Action is aiming to put pressure on GOP House members in districts where Trump received less than 50 percent of the vote, the newspaper company's Washington, D.C. bureau reported.

The OFA grew out of Obama's campaign infrastructure, according to McClatchy. The former president has no formal role with the organization.

Reps. Carlos Curbelo of Florida, Darrell Issa of California, Leonard Lance of New Jersey and Pete Sessions of Texas are among those targeted by the group.

"Look, there's a reason it's called the House of Representatives — you're actually supposed to go to Washington and represent the people you serve," said Jesse Lehrich, OFA's spokesman.

"If the majority of your constituents voted against this administration's platform, and yet you're consistently rubber stamping extreme White House-backed policies that harm families in your district, you're not doing your job. And you need to be held accountable."

McClatchy noted the organization has already set up a webpage for the campaign: Rubber Stamp Reps.

"The majority of the constituents in these districts voted against the administrations platform, yet their representatives are acting as rubber stamps for the White House's extreme agenda rather than working for the people they represent," the webpage reads.

The group intends to concentrate on grassroots organizing and digital ads to label the congressmen as "rubber stamps" for the president, McClatchy said.

It does not directly lobby people to vote for or against lawmakers.

But the group does intend to "call out" lawmakers for what it terms "unacceptable vote on key issues," according to The Hill.

"This will be a sustained and multi-faceted operation running into 2018, including actions calling out lawmakers for unacceptable votes on key issues; volunteer-driven efforts to engage residents within these districts and build real grassroots infrastructure there; and digital assets to support this program," OFA said in a statement.
