President Trump's counterterrorism adviser is under fire from his peers — and Sebastian Gorka is hitting back.

Just ask Michael Smith. He's a counterterrorism expert in Charleston, S.C., who specializes in online recruiting efforts and who has advised members of Congress on terrorism-related issues.

Smith says that at about 7 p.m. Tuesday, he received a call on his smartphone from a private number in Falls Church, Va. It was Gorka — not calling from a government line at his office at the White House.

If President Trump wants to keep his promise to send new detainees to the detention center at Guantanamo Bay, there's plenty of room.

"We haven't received any orders to take additional detainees in," says Navy Capt. John Filostrat. "But if given the order, we could go ahead and comply."

The very first questions of the witnesses at today's hearing was not about Russia. It was about Julian Assange, the founder of WikiLeaks. The website has posted thousands of Democratic officials' emails among other private documents.

After nearly an hour's flight north from Baghdad, a cavernous C-130 military cargo plane touches down. Aboard are reporters, Pentagon officials and the man who has occasioned this trip, Defense Secretary Ashton Carter.

The plane taxis along an airstrip that as recently as July was controlled — and then largely destroyed — by Islamic State fighters.

This is the Qayyarah Airfield West, just 30 miles south of Mosul.

Congress had a full seven months to block a rule change for federal courts that lets judges authorize the hacking of digital devices well beyond their districts.

But after a September attempt in the Senate to vote on the measure failed, opponents on Capitol Hill waited until the day before the rule change was to take effect to introduce three motions aimed at shooting it down or at least delaying its implementation.

Among the many unknowns hanging over this presidential transition: the fate of the U.S. military prison at Guantanamo Bay, Cuba. President Obama has sworn to close it; President-elect Trump wants to fill it up again.

Obama has been promising the closure will happen since his second day in office in 2009. In February, he repeated that pledge one more time, saying, "I'm absolutely committed to closing the detention facility at Guantanamo."

That same day, at a campaign rally in Sparks, Nevada, Donald Trump was promising the opposite.

The U.S. and Russia are the world's two mightiest nuclear powers, and yet over the years, they've made deals to reduce their respective arsenals.

Just like a marriage gone bad, though, things have soured between Washington and Moscow. Bickering over nuclear issues has increased markedly in recent months, with each side accusing the other of cheating.

And that war of words is being matched by actions:

Edward Snowden, the former National Security Agency worker, is back in the news. On Capitol Hill, a House committee met in secret today. Members approved a new report about how Snowden leaked classified documents from the NSA three years ago.

They are often called the "missing 28 pages," and while they are not exactly missing, they are back in the news again.

They are, more precisely, the final 28 pages of a massive 2002 congressional report on the Sept. 11 attacks that runs more than 850 pages. Those last few pages have never fully been made public and they deal with the highly sensitive question of foreign financing of the suicide hijackers who carried out those attacks.

The war over government access to encryption is moving to the battlefield on which Apple told the Justice Department it should always have taken place: Capitol Hill.

The leaders of the Senate Intelligence Committee have introduced a bill that would mandate those receiving a court order in an encryption case to provide "intelligible information or data" or the "technical means to get it" — in other words, a key to unlock secured data.

More than 50 world leaders are attending a nuclear security summit in Washington this week. But Vladimir Putin is a no-show. And, as if on cue, North Korea fired a ballistic missile on Friday.

These biannual nuclear summits, aimed at locking down fissile material worldwide that could be used for doomsday weapons, were proposed by President Obama back in 2009, barely two months into his presidency.

"We must insure that terrorists never acquire a nuclear weapon," he declared, calling such a scenario "the most immediate and extreme threat to global security."

And now we have an update on President Obama's drive to close the prison-for-terror suspects at Guantanamo Bay, Cuba.
