A pair of Senate Democrats is asking the government's top ethics watchdog to hand over details on how Ivanka Trump is avoiding ethical and financial conflicts of interest.
"We write today to request information about the ethics rules that President Trump's daughter, Ivanka Trump, will be required to comply with, or has indicated she will voluntarily comply with, in her role as an advisor to the President," the senators wrote in the letter to Walter Shaub, the director of the OGE.
They also want to know how OGE will make sure the first daughter complies with ethics rules.
The letter comes as Ivanka Trump's influence in the White House appears to be on the rise. She is poised to get an office in the West Wing and was invited to attend the W20 summit by German Chancellor Angela Merkel.
The two senators want to know if OGE has provided guidance, or if the White House has asked for guidance, on what ethics rules apply to Ivanka Trump, and if OGE or White House legal counsel could take disciplinary actions against the president's elder daughter, who isn't a government employee.
They also want to know who, if anyone, was involved in deciding what role Ivanka Trump would play in the White House, and if OGE was involved in the decision.
Warren and Carper are also asking if the first daughter were a government employee, what financial disclosure and ethics rules would apply.
The first daughter has said that she will voluntarily follow any ethics guidelines that apply to federal government employees.
