'Start Here': FBI assuming Pensacola shooting as terrorism & House Judiciary committee to hear impeachment evidence

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

It's Monday, Dec. 9, 2019. Let's start here.

1. Deadly shooting investigation

The FBI says it is working on the assumption that last week’s deadly shooting at Naval Air Station Pensacola was an act of terror.

Three people were killed in the attack on Friday morning.

ABC News’ Josh Margolin tells “Start Here” that investigators are also probing a report that the alleged shooter, Saudi national Mohammed Ashamrani, watched mass-shooting vides in the days leading up to the attack.

2. Presentation day

The House Judiciary Committee will hear today from both Democratic and Republican attorneys, who will present evidence gathered in the ongoing impeachment inquiry against President Donald Trump.

ABC News’ Katherine Faulders tells the podcast that Democrats will likely split up the articles of impeachment into three separate “buckets:” “We're hearing abuse of power, obstruction and bribery.”

3. Investigating the investigators

The Department of Justice inspector general is set to release its findings today after investigating allegations of bias at origins of the Russia investigation.

ABC News Senior Investigative reporter Aaron Katersky explains that at issue for Republicans is the FISA warrant secured by the FBI to open surveillance against former Trump campaign staffer Carter Page: “Republicans have long argued that the application that the FBI used was flawed and tainted with political bias.”
