WASHINGTON, July 30 (Reuters) - The U.S. Senate is

expected to pass major online child safety reforms in a vote on

Tuesday, although the legislation, which has drawn mixed

reactions from the tech industry, faces an uncertain fate in the

House of Representatives.

Two bills - the Children and Teens' Online Privacy

Protection Act and the Kids Online Safety Act, nicknamed COPPA

2.0 and KOSA - would need to pass in the Republican-controlled

House, currently on recess until September, to become law.

The bills were approved by the Senate in a bipartisan

procedural vote last week, with 86 senators supporting and just

one opposing. Democrats control that chamber by a margin of

51-49 seats, while Republicans hold the House by 220-212.

COPPA 2.0 would ban targeted advertising to minors and data

collection without their consent, and give parents and kids the

option to delete their information from social media platforms.

Top U.S. social media platforms made an estimated $11

billion in advertising revenue from users younger than 18 in

2022, according to a Harvard study published last year.

KOSA would make explicit a "duty of care" that social media

companies have when it comes to minors using their products,

focusing on design of the platforms and regulation of the

companies.

Executives at social media sites Snap Inc ( SNAP ) and X

said at a congressional hearing in January that they supported

KOSA, while Facebook and Instagram owner Meta Platforms ( META )

CEO Mark Zuckerberg and TikTok Chief Executive Shou Zi Chew said

they disagreed with parts of it.

Tech industry groups and the American Civil Liberties Union

have criticized the bill, saying that differing interpretations

of harmful content could result in minors losing access to

content related to vaccines, abortion or LGBTQ issues.

Senators amended the language of the bill in response to

such concerns earlier this year, in part by limiting the

enforcement responsibility of states' attorneys general.

Josh Golin, executive director at Fairplay for Kids, a group

that supports the bills, said KOSA requires companies to

mitigate specific risks, such as content that promotes eating

disorders.

"Obviously government officials can do things that are not

legal, but this does not give government officials any legal

basis for censorship," he said.
