'Start Here': Michael Bloomberg considering presidential run and military technology 'Made in America' fraud

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

It's Friday, Nov. 8, 2019. Let's start here.

1. Bloomberg considering

Former New York City Mayor Michael Bloomberg is considering entering the Democratic presidential primary and will file as a candidate in Alabama today, the state's early filing deadline.

If the billionaire businessman joins the race, it would be widely viewed as a statement on former Vice President Joe Biden's viability and whether he can defeat President Donald Trump in 2020, according to ABC News Political Director Rick Klein on "Start Here."

"[Biden] has had a lot of trouble raising money and people have been concerned about his candidacy," he says. "This I think will underscore those concerns."

2. 'Campaign of slander'

House Democrats released a transcript of the closed-door testimony from George Kent, a deputy assistant secretary at the State Department, who said President Donald Trump's personal attorney Rudy Giuliani conducted a "campaign of slander" and "lies" against the U.S. ambassador to Ukraine, Marie Yovanovitch.

"He is basically painting a picture of this Rudy Giuliani-led rogue diplomacy in Ukraine," ABC News' Trish Turner tells the podcast.

Both Kent and Yovanovitch are among the key witnesses set to testify in public hearings next week as Democrats prepare to present their case for impeachment.

"Democrats have a really tough job ahead of them right now," says ABC News Senior Editorial Producer John Santucci. "They are going to try to keep these hearings under control... [and] make it digestible for the American people."

3. 'Made in China'

New York firm Aventura Technologies is accused of selling security equipment made in China with false "Made in the USA" labels to U.S. government agencies, according to federal prosecutors who said the products had known cyber vulnerabilities.

"The American military relies on products being what they are and not being potential spy vehicles for China," ABC News' Aaron Katersky tells "Start Here" today. "We know that the United States already has concerns about China infiltrating sensitive American technology. This may have given them an actual camera into some sensitive spots."
