President Trump said he plans make an announcement about a new round of tariffs today, which he has dubbed "Liberation Day.

Trump made his way back to the White House in no small part because of his promise to better the economy. He's staking a large part of his agenda on broad-based tariffs.

The tariffs are expected to follow similar recent announcements of 25 percent taxes on auto imports; levies against China, Canada, and Mexico; and expanded trade penalties on steel and aluminum.
