Reps. Mike Conaway and Adam Schiff, who are leading the committee's probe, say the panel approved the subpoenas to compel certain individuals to testify and to obtain personal documents and business records.
In addition to those four subpoenas, the committee issued three others - to the National Security Agency, the Federal Bureau of Investigation and the CIA - for information about requests government officials made to unmask the identities of U.S. individuals named in classified intelligence reports. The reports identified the three as former U.N. Ambassador Samantha Power, former National Security Adviser Susan Rice and former CIA Director John Brennan.
The president was reportedly referring Comey's FBI's investigation into Flynn.

Rep. Devin Nunes, R-Calif., the chairman of the committee, created a stir in March when he told reporters he'd seen secret documents that backed President Donald Trump's claims that President Barack Obama had "wiretapped" his offices.
The committee is mounting one of several probes into alleged meddling by Moscow in last year's presidential election, and any collusion with the Trump campaign. "We will continue to pursue this investigation wherever the facts may lead", their statement said.
Subpoenas went to Trump's former national security advisor, Michael Flynn, and to the president's longtime personal attorney, Michael Cohen.
Senate intelligence chairman Richard Burr of North Carolina and vice chairman Mark Warner of Virginia floated the prospect of holding Flynn in contempt of Congress if he continued withholding the documents.
The panel is investigating Russian efforts to influence the United States election, as well as leaks of classified information and reports that identities of Trump associates captured in spy intercepts may have been improperly unmasked.

Trump has repeatedly denounced the investigation as a "witch hunt", claiming it is being perpetuated by "fake news" organizations. The president reportedly told Comey, "I hope you can see your way clear to letting this go, to letting Flynn go".
The subpoenas mark new signs of life in the House committee's investigation, which seemed to stall after Comey's testimony.
"I don't take much" from the subpoenas issued related to unmasking requests, Deitz said.
Cohen told ABC News that he had been asked by both the House and Senate intelligence committees to provide information and testimony about contacts he had with Russian officials.
The Times reported that the peace plan was the work of Felix Sater, a business associate who has helped Trump try to find business in Russian Federation, and Cohen.
