Did you ever speak to the president

about this complaint?”

Congress is investigating allegations

that President Trump pushed a foreign government

to dig up dirt on his Democratic rivals.

“It's just a Democrat witch hunt.

Here we go again.”

At the heart of an impeachment inquiry

is a nine-page whistle-blower complaint

that names over two dozen people.

Not counting the president himself,

these are the people that appear

the most:

First, Trump's personal lawyer, Rudolph Giuliani.

According to documents and interviews,

Giuliani has been involved in shadowy diplomacy

on behalf of the president's interests.

He encouraged Ukrainian officials

to investigate the Biden family's activities

in the country, plus other avenues that

could benefit Trump like whether the Ukrainians

intentionally helped the Democrats during

the 2016 election.

It was an agenda he also pushed on TV.

“So you did ask Ukraine to look into Joe Biden.”

“Of course I did!”

A person Giuliani worked with, Yuriy Lutsenko,

Ukraine's former prosecutor general.

He pushed for investigations that would also

benefit Giuliani and Trump.

Lutsenko also discussed conspiracy theories

about the Bidens in the U.S. media.

But he later walked back his allegations,

saying there was no evidence of wrongdoing by the Bidens.

This is where Hunter Biden comes in,

the former vice president's son.

He served on the board of a Ukrainian energy company

run by this guy, who's had some issues with the law.

While Biden was in office, he along with others,

called for the dismissal of Lutsenko's predecessor,

a prosecutor named Viktor Shokin,

whose office was overseeing investigations

into the company that Hunter Biden was involved with.

Shokin was later voted out by the Ukrainian government.

Lutsenko replaced him, but was widely criticized

for corruption himself.

When a new president took office

in May, Volodymyr Zelensky,

Zelensky said that he'd replace Lutsenko.

Giuliani and Trump?

Not happy.

They viewed Lutsenko as their ally.

During a July 25 call between Trump

and the new Ukrainian president,

Trump defended him, saying, “I heard

you had a prosecutor who is very good

and he was shut down

and that's really unfair.”

In that phone call, Trump also allegedly asked

his counterpart to continue the investigation

into Joe Biden, who is his main rival in the 2020 election.

Zelensky has publicly denied feeling pressured by Trump.

“In other words, no pressure.”

And then finally, Attorney General William Barr,

who also came up in the July 25 call.

In the reconstructed transcript,

Trump repeatedly suggested that Zelensky's

administration could work with Barr and Giuliani

to investigate the Bidens and other matters

of political interest to Trump.

Since the whistle-blower complaint was made public,

Democrats have criticized Barr for dismissing allegations

that Trump had violated

campaign finance laws during his call with Zelensky

and not passing along the complaint to Congress.

House Democrats have now subpoenaed several people

mentioned in the complaint, as an impeachment inquiry

into the president's conduct continues.
