A recently ousted counterterrorism chief says the country is risking the gains made against terrorist threats by cutting back resources with little or no public debate. In an interview with NPR, Russ Travers also expressed frustration at the poor state of relations between the intelligence community and the Trump administration.

The National Security Agency, as well as its counterparts in Britain and Canada, all said Thursday that they're seeing persistent attempts by Russian hackers to break into organizations working on a potential coronavirus vaccine.

The Western intelligence agencies say they believe the hackers are part of the Russian group informally known as Cozy Bear. The intelligence agencies refer to it as APT29.

Russian military intelligence, known as the GRU, was founded a century ago under the leadership of the revolutionary Leon Trotsky.

Only in recent years has it come to the fore with a series of brazen actions. They include Russia's military operations in Ukraine and Syria and the hack of Democratic Party emails in the 2016 U.S. election.

President Trump has said he was not told about a suspected Russian bounty program to pay the Taliban to kill U.S. troops in Afghanistan.

Many immigrants have inspiring stories. Then there's Janis Shinwari, who worked eight years as an Afghan interpreter with the U.S. military in some of the most dangerous parts of his homeland.

"During his service, he saved the lives of five American soldiers. That is not something many people can say," Ken Cuccinelli, the acting director of Citizenship and Immigration Services.

President Trump on Sunday ordered National Guard troops to start withdrawing from Washington, where the protests over the killing of George Floyd have been peaceful in recent days.

In a telephone briefing with reporters, Army Secretary Ryan McCarthy said guardsmen from 11 states, who came to assist the D.C. National Guard, will be returning home over the next two or three days.

Altogether, the National Guard force from D.C. and the states totaled more than 5,000 this past week, though only about one-third were on the streets at any given time, he said.

The race to defeat the coronavirus can be viewed in two very distinct ways. One is based on international cooperation, with a vaccine treated as a "global public good." The other is competitive, a battle between nations that's being described as "vaccine nationalism."

Many are hoping for the former, but are seeing signs of the latter.

Despite Democratic opposition, the Republican majority in the Senate on Thursday confirmed U.S. Rep. John Ratcliffe, R-Texas, as the new director of national intelligence, overseeing all 17 intelligence agencies.

With the 49-44 vote along party lines, Ratcliffe becomes the fourth person to hold the job in less than a year.

He takes over at a sensitive moment. U.S.-China tensions are rising over the coronavirus pandemic, and many in the national security community say they are certain that Russia again will attempt to interfere in the U.S. presidential election this fall.

As researchers around the globe race to develop a coronavirus vaccine, U.S. authorities are warning American firms to exercise extreme caution in safeguarding their research against China and others with a track record of stealing cutting-edge medical technology.

So far, the coronavirus has hit hardest in wealthy countries. But the pandemic now appears poised to explode in many parts of the developing world — which has far fewer resources to combat the virus.

The virus initially traveled outward from China to places that had the most interaction with China. These are the richer parts of East Asia — South Korea, Japan, Taiwan, Singapore — along with Europe and the United States. All these places had lots of flights, business dealings and tourism with China.

When the U.S. government took its first satellite photos in 1960, it wasn't easy getting those pictures back to Earth.

After the satellite took the pictures, the film was dropped from space in a capsule attached to a parachute. A military plane with a large hook flew by to collect the capsule in midair over the Pacific Ocean.

When it comes to U.S. national security, one foreign company sets off alarm bells like no other: Huawei, the Chinese telecom giant.

Huawei scored a key victory, and the U.S. suffered a significant setback, when the company received the green light to build up to 35% of Britain's 5G cellular phone network.

The U.S. government says it's on high alert for cyberattacks from foreign countries in this election year. Yet private cybersecurity firms have often been the ones sounding the alarm, and in some cases, they are selling their services to the U.S. intelligence community.

"We've seen Iran impersonating political candidates," said Sandra Joyce, the head of global intelligence at FireEye, a leading cybersecurity company.

Iraq has been dealing with widespread protests for months, but these demonstrations have been directed at the country's weak, faltering government — and not the U.S.

A newly released watchdog report on how the FBI carried out the Russia investigation offers something for everyone.

The report, the work of Justice Department Inspector General Michael Horowitz, found that the FBI had ample evidence to open the investigation into the 2016 Trump campaign and its links to Russia. For Democrats, that was long-awaited vindication.

Republicans seized on the report's sharp criticism of the FBI, which suffered from "serious performance failures" as it pursued surveillance warrants against one of Trump's campaign advisers, Carter Page.

Mike Lofgren is the very definition of a civil servant. He was a congressional staffer for 28 years, with most of that time spent crunching numbers on the Senate and House budget committees.

He's moderate and mild-mannered, saying, "I was on the Republican side my whole career. I wasn't a culture wars Republican, basically a fiscal conservative in the manner of say, [President Dwight] Eisenhower."

In a July 25 conversation with Ukrainian President Volodymyr Zelenskiy, President Trump asked for an investigation of former Vice President Joe Biden and his son Hunter Biden for their activities in Ukraine several years ago.
