Republicans in Congress and their conservative allies are demanding details about federal workers' use of encrypted messaging apps, part of a broader counterattack on employees suspected of opposing President Donald Trump's agenda.

Congressional Republicans are also pondering changes to longstanding laws that protect government workers, further stoking fears among some federal employees that the new administration's supporters are out to squash dissent.


Republicans on the House Science Committee took up the cause on Tuesday by asking EPA's inspector general to review reports that agency employees are using an app called Signal, which allows people to exchange encrypted text messages and phone calls. POLITICO reported this month that a group of fewer than a dozen EPA employees were using the app to discuss what they would do if Trump's political appointees flout the law or delete valuable scientific data.

The anti-Trump resistance has infuriated Republicans, who fear that dissenters in the government could undercut the president's policy proposals by unleashing even more embarrassing leaks. They also contend that the use of encrypted messaging circumvents federal record-keeping laws — an argument Science Chairman Lamar Smith (R-Texas) echoed in Tuesday's letter.

"[T]he Committee is concerned that these encrypted and off-the-record communication practices, if true, run afoul of federal record-keeping requirements, leaving information that could be responsive to future Freedom of Information Act (FOIA) and congressional requests unattainable," wrote Smith, who organized the letter to the IG. The panel has jurisdiction over many cybersecurity issues.

Outside conservative groups have launched similar efforts.

Citing POLITICO's story, the Cause of Action Institute, a right-leaning watchdog group, filed a request under the Freedom of Information Act this month seeking EPA employees' communications using Signal. "The bottom line is: An encrypted app is basically a way to avoid transparency," Institute Assistant Vice President Henry Kerner said in an interview.

It's not just encryption that is raising eyebrows. Republican research firm America Rising filed a FOIA request this month seeking all emails sent by John O'Grady, a top union official at the EPA, that "mentions or refers to President Trump."

The FOIA request came in response to O'Grady's comments to The Washington Post that Trump's decision to firing then-acting Attorney General Sally Yates "sends kind of a chilling effect" through agencies. O'Grady did not respond to a request for comment.

"The public is entitled to know whether career federal government employees are engaged in partisan politics on the taxpayers’ dime," said Allan Blutstein, vice president of FOIA operations at America Rising.

EPA employees said they are not using Signal for official government business, and they raised concerns that they're being targeted because they are critical of Trump.

"I don't think anybody can dictate which apps we use on our personal time, for personal conversations," one EPA employee told POLITICO.

The debate comes as employees across the government — political appointees and career officials alike — are increasingly relying on encrypted messaging apps, fearing repercussions if their private conversations are made public.

National security officials have long used encrypted mobile phone software like Signal and WhatsApp to communicate with reporters and other staffers. Signal frequently comes up in articles advising people how they can communicate free of snooping from government officials or hackers, especially following the massive leaks of stolen Democratic Party emails that roiled last year's presidential election.

Trump's appointees have gotten into the act, too: The Washington Post reported this week that administration staff members are using an app called Confide, which deletes messages once they are read, because they're afraid of being accused of leaking to the press. That's also a threat to transparency and accountability, argued Tom Fitton, president of the conservative activist group Judicial Watch, in an interview with POLITICO on Tuesday.

“If they're conducting government business via an application that destroys records, that’s a problem that needs to stop,” said Fitton, adding that the administration needs to either train its staff on the issue or send them a reminder. He added that the Trump administration is “asking for a lawsuit from either Judicial Watch or someone else if they don’t get their act together on these records policies."

Asked if the House Science Committee will pursue a similar probe of White House staffers' use of encrypted messaging apps, spokeswoman Kristina Baum declined to make any commitments. But she said the panel "intends to continue to monitor" cyber issues.

The growing tension across the government has some career employees worried that Republicans will try to make radical changes to laws protecting federal workers — a move that could make people more fearful to speak out against Trump. Trump has already imposed a freeze on most federal hires and has promised to reduce the size of the workforce.

"Frankly, the climate has shifted rather dramatically and we’ve gone from a chief executive who respects civil servants to a rather bombastic, disdainful chief executive who unfortunately empowers their disparagement," Rep. Gerry Connolly (D-Va.) said in an interview.

Rep. Jason Chaffetz (R-Utah), chairman of the House Oversight Committee, is eyeing a major overhaul of the civil service system. He has discussed phasing out pensions for new government employees, instead relying on a defined-contribution plan like a 401(k), and has advocated making it easier to fire problem workers. Chaffetz reportedly talked about some of these issues during a recent meeting with Trump.

Connolly said he's concerned that the Republican Congress could win enough support to move a bill gutting civil service protections. "It is very alarming and I think frankly very destructive in terms of the fabric of a free government and a free society," he said.

In the Senate, lawmakers are also considering changes to civil service laws, but Sen. James Lankford (R-Okla.) said he is eyeing targeted tweaks that can win bipartisan support, such as efforts to improve the hiring process.

"If we can keep it small and we can keep it targeted, I think we can move it through unanimous consent," said Lankford, who chairs the Homeland Security and Governmental Affairs Committee's panel on regulatory affairs and federal management. "We need to be better at hiring. If we’re better at hiring we don’t have to worry about firing."
