On Wednesday, the Trump administration allowed some suppliers to restart sales with the Chinese telecom after it was placed on a blacklist for national security threats over the summer. 

The Commerce Department started issuing licenses on Wednesday to some US firms to conduct business with Huawei. One US official told Reuters that 300 license requests were filed, and half of those requests were processed by late Wednesday. Another source told Reuters that most of the licenses were for sales of cell phone and non-electronic parts. 

But by Thursday, a bipartisan group of 15 US senators had enough with President Trump's games. They demanded the administration to halt the Commerce Department from issuing licenses immediately. 

Senators wanted the administration to provide Congress with a detailed report outlining specific criteria for determining whether or not the approval of any license poses a national security threat."
