Steve Mnuchin just had to remind Trump to sign the symbolic tariff document

President Donald Trump signed a symbolic bill that puts new tariffs on foreign steel and aluminum. The document wasn't a piece of legislation or an executive order, but it was revealed that Trump wanted a ceremony and wanted to sign something and the White House had to scramble.

Thus, today, Trump joined with steel workers in the White House. Toward the end of his speech he asked the workers if they wanted to come into the Oval Office for a photo.

However, Treasury Secretary Steve Mnuchin had to remind the president to actually sign the document. In the past, Trump has left the room after his speech and forgotten to sign it. In another instance, Vice President Mike Pence had to stop Trump from walking out before signing it.

Republicans are not happy with Trump over the tariff.
