A controversial U.S. private security firm signaled Friday it is slated to return to business, spurring questions of whether President Trump will seek to privatize the ongoing war in Afghanistan.

Blackwater took out a full-page ad in the latest edition of Recoil magazine with the message: “We are coming," the Military Times reported on Friday. The ad comes a day after Defense Secretary Jim Mattis announced he would resign from his post and word emerged that President Trump will draw down troops in Afghanistan.

Former founder Erik Prince sold the company in 2010, but has maintained communications with Trump and reportedly pressed him to employ private contractors in Afghanistan, where the U.S. is said to be preparing to withdraw nearly 7,000 troops.

Prince — who has also been interviewed by special counsel Robert Mueller as part of his investigation into whether Trump colluded with the Russians during the 2016 election — does not have any known relations to the Constellis Group, the new name put on the company after it was purchased by Apollo Holdings Group. The firm reportedly shelved plans earlier this year to try to sell the Constellis Group.

The tease about a return to business comes after a federal judge on Wednesday found a former Blackwater guard guilty for his role in a 2007 shooting in Baghdad, long considered a low-point in the 17-year-old conflict.
