The tenure of David Sacks, the "Crypto Tsar" of the United States, has sparked controversy, with allegations of possible violations and exceeding limits.

American "encryption czar" David Sacks has recently become embroiled in a term limit controversy, with a group of U.S. lawmakers led by Senator Elizabeth Warren questioning whether he has violated federal appointment regulations.

Sachs serves as a special advisor on artificial intelligence and cryptocurrency affairs at the White House, in the capacity of "Special Government Employee" (SGE), which by law cannot exceed 130 working days per year.

According to statistics, since President Trump took office on January 20 of this year, there have been a total of 167 working days. This means that Sachs must take at least 37 days off for his tenure to comply with the legal limit of 130 days. Lawmakers are calling for Sachs to publicly disclose the specific number of days in office to clarify whether there have been any violations.

In response to the above doubts, a spokesperson for Sachs publicly stated that Sachs has always "managed its days in office with caution," ensuring that the number of working days remains within limits, and emphasized that they should not be calculated consecutively by working days. The spokesperson also mentioned that Sachs strictly adheres to ethical standards and has not exceeded legal limits.

This controversy is not the first time that Sachs has been scrutinized by Congress. In March of this year, Warren had already questioned his potential conflicts of interest in the encryption field, demanding that he prove he has cleared his personal digital asset holdings.

When Sachs was appointed to his current position in December 2024, there was industry expectation for his promotion of cryptocurrency-friendly policies. However, the ongoing controversies surrounding the compliance and ethical risks of his tenure may affect the formulation and advancement of related policies.

The situation is still developing, and the White House has not yet issued an official comment on this matter. Market and policy observers are closely monitoring subsequent developments and the potential impact on U.S. encryption regulatory policies.
