U.S. Sen. Michael Bennet is challenging President Donald Trump’s pledge to donate all profits from foreign governments patronizing his hotels to the U.S. Treasury, noting all the businesses bearing the president’s name should fall under the commitment.

In a letter sent last week to White House Counsel Donald McGahn, his third to the Trump administration on the matter, the Democratic Colorado senator expressed concerns about the foreign policy and national security implications of the president’s alleged conflicts of interest.

“As I have said before, the president’s ethics arrangement is wholly inadequate and does not take the needed steps to address, much less eliminate, significant conflicts of interests,” Bennet said in the letter.

In January, Trump promised to donate all the profits in an effort to avoid conflicts of interest. A Politico report said the Trump administration will start making those donations in 2018. Trump’s attorneys have maintained the president is not legally required to donate those profits, while critics say that foreign government patrons staying at a Trump hotel is counter to the constitution.

Bennet said he has seen no plan that explains how the administration will execute the donation commitment and previous statements “have been insufficient.”

“The same conflict of interest concerns that arise from a Trump hotel profiting from a foreign government applies to every business and asset within the Trump organization,” Bennet wrote. “It is extremely concerning that any of the organization’s businesses would potentially be allowed to retain profits from a foreign government-regardless of whether or not it is a hotel.”

In the letter, Bennet outlined that the White House track all profits from foreign governments to ensure all monies reach the U.S. Treasury, and provide public documentation of the donations.

Bennet is also seeking clarification on whether “profits from foreign governments” applies to all aspects of the Trump business empire, and whether “similar businesses” apply to other Trump enterprises including his real estate businesses, golf courses and restaurants among other ventures.

The Trump organization did not immediately respond to a request for comment.

Two earlier Bennet letters in late March and early April asked for full transparency on the Trump organization’s foreign investments, agreements, contracts, debts and loans and warned that foreign companies and government might use the president’s connections to his organization to influence his decisions as president.

The president has also stated he would donate his $400,000 salary as president to the U.S. Treasury. Press Secretary Sean Spicer said in March he will start making those donations at the end of the year.
