In the final weeks of 2019, a top fundraiser for Sen. Susan Collins walked into a perilous meeting at a Corner Bakery in Washington, D.C.

For the first time in her two-decade Senate career, the Republican lawmaker from Maine was in danger of losing her seat. President Donald Trump’s dismal approval ratings were dragging her down in the polls, and she was falling behind her likely 2020 Democratic challenger in fundraising.

Scott Reed, head of the Collins super PAC, was on a mission to close that gap. Reed was meeting that day with three executives from a Hawaiian defense contractor, Navatek. A year earlier, Collins had helped their company land a multimillion-dollar Navy research contract in Maine. Now, seated at a coffee shop not far from the U.S. Capitol, Reed asked them for a $500,000 donation....

Trump administration officials earlier this year killed a federal criminal investigation into the coal empire owned by Sen. Jim Justice, a Republican from West Virginia and a close ally of the president’s.

The investigation examined potential criminal violations of the Clean Water Act by the multistate mining operations largely run by Justice’s son, Jay, according to current and former officials familiar with the matter.

The criminal probe was a significant escalation in the yearslong effort to police serial pollution offenses by Virginia-based Southern Coal and dozens of affiliated mining operations controlled by the family. In the past decade, Southern Coal and other Justice corporations have racked up tens of thousands of alleged violations of the Clean Water Act and have been sued repeatedly by state and federal prosecutors over their failure to properly follow environmental laws at their mining sites....

When top Trump adviser Stephen Miller threatened on May 9 that the administration is “actively looking at” suspending habeas corpus in response to an “invasion” from undocumented immigrants, he was operating on a fringe legal theory that a right-wing faction has been working to legitimize for more than a decade.

“The Constitution is clear — and that of course is the supreme law of the land — that the privilege of the writ of habeas corpus can be suspended in a time of invasion,” Miller said earlier this month in response to a question about Trump’s threat to suspend habeas corpus, the legal right of a prisoner to challenge their detention. Days after Miller’s remarks, Homeland Security Secretary Kristi Noem issued the same warning when a member of a House panel asked her if the number of illegal border crossings meets the threshold for suspending the right. “I’m not a constitutional lawyer,” Noem said. “But I believe it does.”

Hard-liners have referred to immigrants as “invaders” as long as the U.S. has had immigration. By 2022, invasion rhetoric, which had previously been relegated to white nationalist circles, had become such a staple of Republican campaign ads that most of the public agreed an invasion of the U.S. via the southern border was underway. ...
