A federal judge issued a temporary restraining order on Tuesday halting the release of downloadable blueprints of 3D-printed guns, the Associated Press reports.

The backdrop: Leading gun control organizations took the lead in filing an action related to a settlement that allowed an open-source defense firm to release blueprints for guns online.

Several Republican and Democratic lawmakers are emerging as troublemakers within their parties and political thorns for their leadership.

Why it matters: We're calling this group "The Mischief Makers" — members who threaten to upend party unity — the theme eclipsing Washington at the moment — and potentially jeopardize the Democrats' or Republicans' position heading into the 2022 midterms.

President Obama's former speechwriter says he's "preemptively frustrated" with President Biden's effort to find unity with Republicans.

What they're saying: Cody Keenan told Axios that Biden's messaging team has "struck all the right chords," but at some point "they're gonna have to answer questions like, 'Why didn't you achieve unity?' when there's an entire political party that's already acting to stop it."

A Republican group is raising and spending huge amounts of money defending Sen. Josh Hawley after he was ostracized for early January’s attack on the U.S. Capitol.

Why it matters: The Senate Conservatives Fund is plugging Hawley's ideological bona fides and backfilling lost corporate cash with needed political and financial support, helping inoculate him as he weighs reelection or a possible presidential campaign in 2024.
