The dollar fell after Trump fired Attorney General

The dollar has fallen in price on Tuesday during the Asian trading session, after yesterday the US president Donald Trump fired the Acting Attorney General Sally Yates, who ordered the Ministry of Justice lawyers not to embed Trump's ban on immigration, and the Bank of Japan left policy unchanged, as expected, but raised its forecast about growth.
Trump has appointed Dana Boente, Attorney for the Eastern District of Virginia, to the position of Yates, the White House press secretary Sean Spicer wrote on Twitter.
