WASHINGTON, March 12 (Reuters) - The U.S. House of

Representatives plans to vote on a bill on Wednesday that would

give TikTok's Chinese owner ByteDance about six months to divest

the short-video app used by about 170 million Americans or face

a ban.

The vote is expected around 10 a.m. under fast-track rules

that require support by two-thirds of House members for the

measure to pass.

The vote comes just over a week since the bill was proposed

and after one public hearing with little debate. The House

Energy and Commerce Committee last week voted 50-0 in favor of

the bill, setting it up for a vote before the full House.

The FBI, Justice Department and Office of the director of

national intelligence held a classified briefing for House

members on Tuesday.

"We've answered a lot of questions from members. We had a

classified briefing today. So that members can see even more

details about what's at risk and how the CCP (Chinese Communist

Party) can jeopardize the risk to American families," said House

Majority Leader Steve Scalise.

Tiktok CEO Shou Zi Chew will visit Capitol Hill on

Wednesday on a previously scheduled trip to talk to senators, a

source briefed on the matter said.

"This legislation has a predetermined outcome: a total

ban of TikTok in the United States," the company said. "The

government is attempting to strip 170 million Americans of their

Constitutional right to free expression," it added.

Some opponents of the legislation, including Democratic

Representative Maxwell Frost, think the bill will pass in the

House. Frost said many lawmakers who will vote for the bill are

motivated by a desire to protect users, which he supports. Frost

was among four lawmakers out of the 432-member House that held a

press conference opposing the bill.

"The problem is the process here, the fact that it's been

steamrolled and people really can't digest the consequences,"

Frost said. "I would like to see TikTok ownership changed, but

not at the expense of our First Amendment rights, business

owners and content creators."

The fate of the legislation is uncertain in the U.S.

Senate, where some senators want to take a different approach.

President

Joe Biden

said last week that he would sign the bill.

White House national security adviser Jake Sullivan said

on Tuesday that the goal is ending Chinese ownership - not

banning TikTok. "Do we want TikTok, as a platform, to be owned

by an American company or owned by China? Do we want the data

from TikTok -- children's data, adults' data -- to be going, to

be staying here in America or going to China?"

It is unclear if China would approve any sale or if

TikTok could be divested in six months

The bill would give ByteDance 165 days to divest TikTok.

If it failed to do so, app stores operated by Apple ( AAPL ),

Alphabet's Google and others could not legally offer

TikTok or provide web hosting services to ByteDance-controlled

applications.

In 2020, then-President Donald Trump sought to ban

TikTok and Chinese-owned WeChat but was blocked by the courts.

In recent days he had

raised concerns about a ban
