A group of Senate Democrats called on President Trump Thursday to release the visitor logs at both the White House and his personal properties, where he has spent a lot of time during the early days of his administration.

In a letter to the White House, the group of seven senators — Sens. Sheldon Whitehouse, D-R.I., Elizabeth Warren, D-Mass., Tom Udall, D-N.M., Tom Carper, D-Del., Ed Markey, D-Mass., Tammy Duckworth, D-Ill., and Martin Heinrich, D-N.M. — called on the administration to become more transparent and to follow the Obama White House by releasing the visitor logs.

"Secrecy is becoming the hallmark of the Trump White House," they wrote in the letter, before pushing back against the White House's claim that disclosure would create a national security risk.

"We are not aware of any instance where the disclosure of the name of a visitor to the White House, as long as three months after that visit, created a national security risk," they continued.

"The American public is entitled to know who meets with the President and White House policy makers. There has been strong bipartisan support for releasing the visitor logs and congressional Republicans conducted vigorous oversight over the Obama administration's implementation of its disclosures," the lawmakers wrote.

The group is also calling for the White House to reveal who has been granted waivers from signing the administration's ethics pledge.

"Scandal follows ‎conflict of interest like night follows day," they wrote. "Your decisions permit industry lobbyists to advance their agendas in your administration, confer with former clients and employers to craft government policy behind closed doors, and cash out by returning to their high-paying lobbying jobs to take advantage of those new policies, all thanks to secret waivers that are never made public. When industry captures its regulators, the American people rarely benefit."

The White House announced last Friday that they would not release the visitor logs, creating an uproar from those calling for more transparency from the administration.
