WASHINGTON, D.C. -- A Michigan congressman is requesting a congressional briefing on recent leaks by U.S. intelligence officials tied to allegations about connections between Russian intelligence officials and the Trump administration and its presidential campaign.

U.S. Rep. Justin Amash, R-Cascade Township, on Feb. 17 joined U.S. Rep. Walter Jones, R-North Carolina, in sending a letter to Attorney General Jeff Sessions, FBI Director James Comey and Acting Director of National Intelligence Michael Dempsey.

Amash and Jones request "an immediate briefing for all members of Congress" from the federal officials.

"In recent weeks, several major news outlets have cited leaks from current and former intelligence officials supporting allegations about the current administration and the presidential campaign," the letter states. "These reports allege that members of the Trump Campaign had recurring contacts with senior Russian intelligence officials prior to the election, that phone calls with former National Security Advisor Michael Flynn were recorded by U.S. intelligence, and that the Department of Justice warned the president about General Flynn."

The New York Times reported on Feb. 14 that phone records and intercepted calls show members of Trump's presidential campaign had repeated contact with senior Russian intelligence officials in the year before the election. The newspaper cited "four current and former American officials" as sources of the allegations.

Trump dismissed the claims the next day in a tweet.

"This Russian connection non-sense is merely an attempt to cover-up the many mistakes made in Hillary Clinton's losing campaign," the president tweeted.

The allegations and leaks, combined with the abrupt resignation of Flynn on Feb. 13, all argue in favor of congressional attention to the issue, Amash and Jones argue.

"We recognize that relevant investigations may be ongoing, and your staff may also be responding to informational requests form congressional committees, but the issues raised by these reports are too grave for the vast majority of Congress to be kept in the dark until the completion of those investigations, and so we must insist upon an immediate briefing," their letter states.

This is not the first such request from the two congressmen.

Amash and Jones sent a joint letter to The White House in December asking for a briefing on reports that Russia interfered with November's presidential election.

First elected to Congress in 2010, Amash won reelection to a fourth term in November 2016.

He represents Michigan's 3rd congressional district, which stretches from Albion in the south to Sand Lake in the north and includes all or portions of Barry, Calhoun, Ionia, Kent and Montcalm counties.
