It required the head of the CIA to release annual summaries of US drone strikes and assess how many died as a result.
Mr Trump's executive order does not overturn reporting requirements on civilian deaths set for the military by Congress.
During Mr Obama's eight years in office, 1,878 drone strikes were carried out, according to researchers. Since Mr Trump was elected in 2016, there have been 2,243 drone strikes. The Republican president has also made some of the operations, the ones outside of war zones, more secretive. As a result, things have different today: under Mr Trump, there are more drone strikes - and less transparency.
While the mainstream media focuses on anything but the current state of U.S. intervention in the Middle East, the Trump Administration is breaking records by accumulating a horrific number of civilian deaths.
President Trump has been in office for just 9 months, and he has already surpassed Obama’s murderous record with estimated numbers as high as 4,500 civilian deaths.
