'Start Here': Kavanaugh FBI investigation underway, Tesla settles with SEC and hundreds dead in Indonesia tsunami. What you need to know to start your day. The FBI has begun interviewing witnesses in the Brett Kavanaugh investigation.

It's Monday, Oct. 1, 2018. Here's what you need to start your day:

1. FBI interviews begin in Kavanaugh investigation

An FBI investigation is underway into Christine Blasey Ford’s accusation of sexual assault against Supreme Court nominee Brett Kavanaugh, an accusation he has denied.

Former FBI agent and ABC News contributor Steve Gomez says many of the details offered by Kavanaugh at his hearing about his past behavior will be relevant to investigators.

2. Tesla, SEC settle fraud lawsuit

Elon Musk has been hailed as a visionary. He has also been called a rule breaker. And this weekend, the Securities and Exchange Commission seemed to agree.

On Thursday, the SEC sued Musk for what might be the most expensive tweet ever posted. Just two days later, the two sides arrived at a settlement: The company will pay $20 million, while Musk himself will pay $20 million more and will step down as Chairman of Tesla for at least 3 years, but will remain CEO.

Forbes’ Alan Ohnsman tells us that the most consequential part of the punishment involves the company’s board of directors.

3. Hundreds dead after major tsunami rocks Indonesia

Rescue workers are still trying to get to potential survivors in Indonesia after a 20-foot high tsunami barreled into several coastal towns.

ABC News’ Julia Macfarlane, who witnessed the last major tsunami to hit the country, tell us how the death toll could rise even higher in the coming days.

4. One year since Las Vegas masscare

The one-year anniversary of 58 people being killed by a lone gunman at a country music festival in Las Vegas is Monday.

It remains the deadliest mass shooting in modern American history.

ABC News Senior National correspondent Matt Gutman was there that night, and tells us that the survivors are still dealing with trauma.
