Republican Sen. Marsha Blackburn called on her fellow lawmakers to refuse meetings with representatives from Chinese companies, including video sharing app TikTok and telecom company Huawei, in a letter Thursday.

Why it matters: Companies with ties to China have been the target of ire and suspicion from lawmakers from both parties concerned about privacy and security.

Driving the news: Blackburn told colleagues that denying access to Senate offices sends a "warning shot" to Beijing in the misinformation war over the origins of the coronavirus.

  • Banning meetings with Huawei, TikTok, telecom company ZTE, and drone-maker DJI "is a long overdue sanction," she wrote, pointing to bans on government agencies using Huawei and ZTE equipment, and rules against some federal employees using TikTok on government devices.
  • "Their company representatives likewise cannot be trusted to lobby members of Congress with the best of U.S. intentions in mind," Blackburn wrote.

What they're saying:

  • "Contrary to Senator Blackburn’s misinformation, DJI’s American employees welcome every opportunity to discuss issues related to drone technology with our elected officials, helping them to better understand the technology that American first responders rely upon to save lives," DJI said.
  • "TikTok US is led and run by a team of experienced and empowered industry veterans in LA, Silicon Valley, New York, Austin and other cities throughout the country," a spokesperson for the company said. "We believe that open dialogue is the best way for people to learn about our values and policies. We will continue to engage with policymakers who are interested in learning what TikTok stands for."

Setting the odds on a TikTok deal

The TikTok shot clock is down to just 25 days, by which time it either has a deal for its U.S. business or has a presidential shutdown notice pinned to its back.

The state of play: Everyone is taking this timeline very seriously. It's possible that President Trump would give an extension, or find another rhetorical wriggle to save millennial face, but those close to the situation say it's a risk they have no intention of taking.

Crypto leads to massive surge in online scams

Bogus cryptocurrency investments led to an unprecedented increase in online scams last year, according to new data from the Federal Trade Commission (FTC).

Why it matters: Cryptocurrency is an easy target because while it's surging in popularity, there's still a lot of confusion about how it works.

  • Other factors include a person having Type 2 diabetes or the reactivation of the Epstein-Barr virus.
