Liberal billionaire George Soros's advocacy arm is ramping up its lobbying efforts this year, disclosure forms show.

The deep-pocketed Democratic financier increased lobbying expenditures on a range of foreign issues, including efforts to oppose laws described as a direct attack on his funding of non-governmental organizations (NGOs) in his native country of Hungary.

The Open Society Policy Center, a D.C.-based nonprofit that focuses on advocacy efforts and is a separate entity from the Soros grant making Open Society Foundations, has spent nearly as much on lobbying in the first half of 2017 as the group did in the entirety of 2016.

The Open Society Policy Center reported spending $4.6 million in the first and second quarters, which runs from Jan. 1 to June 30, according its disclosure forms filed to the House of Representatives and the Senate. The group has three in-house lobbyists who lobby the U.S. Senate, House of Representatives, National Security Council, the Department of Defense, and the Department of State.
