Microsoft, for example, is one of several tech firms -- others include Amazon, Alphabet, Apple and Facebook -- that are reportedly drafting a letter to Trump spelling out their objections to and concerns over the travel ban.
A preview of the letter was forwarded to some media outlets, including Recode. "We are concerned ... that your recent executive order will affect many visa holders who work hard here in the United States and contribute to our country's success," the letter said.
Other companies have taken their complaints to court, notably Amazon and Expedia, which filed supporting declarations in a Washington State lawsuit brought by its attorney general.
Neither the Department of State or the Department of Homeland Security responded to requests for comment on Microsoft's request.
