White House spokeswoman Sarah Sanders called Brunson's detention "unfair", saying that Trump had spoken with Turkey's Recep Tayyip Erdogan about the pastor.
Speaking privately to journalists late Saturday, President Erdogan broke his silence on the crisis, saying the US can't use sanctions to make Turkey back down. Brunson, who was recently released to home detention, was charged with committing crimes, including spying for the PKK, which is listed as a terrorist group by both the U.S. and Turkey as well as the EU.
The two officials, Minister of Justice Abdulhamit Gul and Minister of Interior Suleyman Soylu, will have their assets and properties under United States jurisdiction blocked and Americans will be prohibited from engaging in financial transactions with them.
The two ministers will have any assets and properties under US jurisdiction blocked and USA persons will be prohibited from engaging in financial transactions with the ministers, CNN reported.
The sanctions are being prepared under the Global Magnitsky Act of 2016, which allows the US government to target individuals, companies or other entities involved in corruption or human-rights abuses anywhere in the world.
Family Research Council President Tony Perkins, who serves on the U.S. Commission on International Religious Freedom, said in a statement: "The president is not acting alone".
Late on Wednesday, Turkey's foreign ministry said it will retaliate against Washington's decision, calling it a "hostile stance".
Turkey's foreign ministry said it had shared "necessary information" with the U.S., but insisted the case should be left with its judiciary.
He wrote: "A total disgrace that Turkey will not release a respected US Pastor, Andrew Brunson, from prison". Pence has said that "there is no credible evidence against" Brunson.
"The aggressive attitude of the US serves no goal", it said in a statement, adding that Turkey would reciprocate "without delay".
Mr Brunson has been in a Turkish jail since October 2016 for allegedly being a threat to national security.
"President Trump concluded that these sanctions are the appropriate action", he said.
On all those issues, Turkey has worked at cross purposes with the United States in recent years and is only more likely to become an irritant more than an ally after the sanctions escalation.
Despite these long-standing and significant ties - not to mention the huge potential to backfire - the Trump Administration had to deliver a message to Erdogan and the Turkish government that imprisoning Americans is not acceptable, according to Eric Edelman, former ambassador to Turkey. Trump has repeatedly lauded Erdogan as a strong leader and, after their meeting last month in Brussels, praised the Turkish president while criticizing other North Atlantic Treaty Organisation leaders.
