PROBLEM: Washington (CNN) President-elect Donald Trump said Monday that Chicago Mayor Rahm Emanuel should seek federal assistance to combat homicides in the nation's third-largest city. "Chicago murder rate is record setting - 4,331 shooting victims with 762 murders in 2016. If Mayor can't do it he must ask for Federal help!" Trump tweeted. Trump's tweet accurately relayed Chicago's homicide numbers. And while they are not "record setting," The Chicago Tribune reports that homicides were up 60% from 2015 to the highest levels in 20 years. Emanuel, who was President Barack Obama's chief of staff from January 2009 to October 2010, met with Trump in New York last month, urging the President-elect to continue the Deferred Action for Childhood Arrivals program until a modernized immigration system can be decided by Congress.Trump has talked about Chicago crime beforeEmanuel's office responded that they are taking the issue seriously

PROBLEM: (CNN) President Donald Trump has bragged -- and did so again during his State of the Union address Tuesday -- that the tax cuts Congress passed would be the biggest in history. There's no doubt the tax legislation slashed corporate tax rates and will give 80% of individual filers a tax cut, according to some estimates. But arguably, President Barack Obama passed a larger tax cut by making most of President George W. Bush's cuts permanent. President Ronald Reagan definitely did. And Presidents John F. Kennedy and Lyndon Johnson probably did, too. "It will be the biggest tax decrease, or tax cut, in the history of our country," Trump said at the White House last month.Trump has said the tax cuts Congress passed would be the biggest everThey would not, according to the way the government measures tax cuts
