'Start Here': Ex-Twitter employees accused of spying for Saudi Arabia and first public impeachment hearings scheduled

Here's what you need to know to start your day.

It's Thursday, Nov. 7, 2019. Let's start here.

Two former Twitter employees are accused of accessing information from private accounts of Saudi government critics and thousands of other users, according to prosecutors.

ABC News Senior Investigative Reporter Aaron Katersky walks "Start Here" through the criminal complaint, "In a country like Saudi Arabia, where Twitter may be the only outlet the dissidents have, the Saudi royal family knew where to find these critics and specifically looked for favorable employees at Twitter to try and get the accounts they wanted."

Twitter in a statement said "sensitive" user information is limited to a "group of trained and vetted employees," adding, "We understand the incredible risks faced by many who use Twitter to share their perspectives with the world and to hold those in power accountable. We have tools in place to protect their privacy and their ability to do their vital work. We’re committed to protecting those who use our service to advocate for equality, individual freedoms, and human rights."

2. Impeachment goes public

House Democrats have announced that public hearings will begin next Wednesday with the top U.S. diplomat in Ukraine, Ambassador William Taylor, and Deputy Assistant Secretary of State George Kent expected to testify.

"A lot of this isn't about lawmakers necessarily getting the answers," she says. "It's about the American people."

3. “Who in the world attacks women and children?”

Mexican authorities said Wednesday that a criminal group known as “La Linea” could be responsible for the massacre of an American family in northern Mexico.

Three women and six children were killed in the attack.

ABC News Chief National Affairs correspondent Tom Llamas joins “Start Here” and says some of the violence has shaken some of these fundamentalist Mormon families living in the region: “A lot of these families going to have to decide what they're going to do, whether they stay put or they end up moving on.”
