Before the start of business, Just Security provides a curated summary of up-to-the-minute developments at home and abroad. Here’s today’s news.

The TRUMP CABINET’S RELATIONSHIP WITH RUSSIA

Then Sen. Jeff Sessions (R-Ala.) spoke with Russia’s ambassador to the US twice last year, according to Justice Department officials, conversations he did not later disclose when asked during his confirmation hearing to become attorney general. Adam Entous, Ellen Nakashima and Greg Miller report at the Washington Post.

“I did not have communications with the Russians.” CNN’s Faith Karimi recalls what Jeff Sessions said about Russia ties during his confirmation hearings.

House Democratic leader Nancy Pelosi called for Sessions to resign as Attorney General yesterday, Reuters reports.

“This is a real and very serious threat to the national security of the United States,” Sen. Elizabeth Warren (D-Mass.) tweeted yesterday, also calling on Sessions to resign. Brooke Seipel reports at the Hill.

“I never met with any Russian officials to discuss issues of the campaign,” Sessions said in a statement late last night. “I have no idea what this allegation is about. It is false.” Charlie Savage reports at the New York Times.

Precedent and law dictate that an FBI investigation must begin to determine if there are grounds to indict Sessions for perjury and an independent prosecutor must be appointed to look into his conduct in particular, and possibly the Trump administration’s ties to Russia in general, argues Jay Michaelson at The Daily Beast.

White house officials in the last days of the Obama administration rushed to spread information about Russian efforts to undermine the presidential election and about possible contacts between now-President Trump’s associates and Russian officials, with two aims: to make sure such interference isn’t repeated in future US or European elections, and to leave a clear paper trail of intelligence for government investigators, Matthew Rosenberg, Adam Goldman and Michael S. Schmidt report at the New York Times.

If the FBI uncovers any criminal activity related to Trump’s aides’ alleged contacts with Russian officials, Attorney General Sessions should step aside to make way for a special prosecutor, Sen. Lindsey Graham (R-S.C.) said yesterday, Mallory Shelbourne reports at the Hill.

The parameters of their investigation into Russian interference with the US election have been set by lawmakers on the House Intelligence Committee, Joe Uchill setting out the main questions they’ll focus on at the Hill.

White House staffers have been told to preserve any material related to Russian interference in the election, the Julie Pace and Vivian Salama report at the AP.

The House of Representatives intelligence committee will investigate allegations of collusion between President Trump’s campaign and Russia, top Democrat on the committee Rep. Adam Schiff said yesterday, Reuters reporting.

The US nearly went to war with Iran at the start of February, when Defense Secretary Jim Mattis wanted the US Navy to intercept and board an Iranian ship to look for contraband weapons possibly headed to Houthi fighters in Yemen,” an operation he ultimately decided to set aside because it was “leaked.” Mehdi Hasan explores this “bizarrely buried” story at The Intercept.

The possibility of military force or regime change to stop North Korea’s nuclear program is included in an internal White House review of strategy on the bellicose nation, Carol E. Lee and Alastair Gale report at the Wall Street Journal.

India’s foreign secretary will undoubtedly focus on defense ties with the US during his visit to Washington this week, where the belief that the US and India are “natural defense partners” enjoys “remarkably widespread agreement,” Benjamin Schwartz writes at the Wall Street Journal.

The White House is fully supportive of using the term “radical Islamic terrorism,” Vice President Pence said yesterday, despite advice from the new national security advisor. Mallory Shelbourne reports at the Hill.

The one subject that could bring Trump’s America and China closer together is the threat of terrorism by Islamist extremists, suggests Adam Taylor at the Washington Post.

Is it not time to “sound the death-knell of American exceptionalism?” Nick Bryant writes at the BBC.

SPECIAL OPERATIONS RAID in YEMEN

Clues about possible future al-Qaeda weapons and training tactics are offered by computers and other devices seized during the Special Operations raid in Yemen in January, according to American officials, though it remains unclear as to how this information will increase the military’s knowledge of plans and future operations by the terrorist group. Eric Schmitt and David E. Sanger report at the New York Times.

Secretary Mattis confirmed as recently as yesterday that “there was significant intelligence” gathered in the raid, Vice President Mike Pence insisted yesterday, Max Greenwood reporting at the Hill.

President Trump’s honoring of the widow of Navy SEAL William “Ryan” Owens during his Congressional speech doesn’t erase the lingering questions surrounding the raid in which he was killed, Democrats said yesterday, Jeremy Herb reporting at POLITICO.

The many questions and issues resulting from the deadly raid in Yemen are analyzed by Missy Ryan and Thomas Gibbons-Neff at the Washington Post.

SYRIA

The US should use its leverage to oblige Russia to split with Iran and abandon the Assad regime, suggests the Washington Post editorial board.

Syrians are increasingly pursuing justice through criminal suits in domestic European courts, relying on the notion of universal jurisdiction – that war crimes have no geographical boundaries – report Anthony Faiola and Rick Noack at the Washington Post.
