Input: Consider Input: (CNN) Donald Trump and Mitch McConnell aren't exactly kissing and making up. The unflattering details of a rapidly deteriorating relationship between the President and the Senate majority leader spilled out into the open this month -- an angry phone call that devolved into a screaming match; a refusal to speak to one another since that heated conversation; and a steady exchange of hardly subtle snubs. But the constant drip of reporting about the stunningly strained ties between Trump and McConnell appear to have done little so far to compel the two powerful Republicans to swallow their pride and hug it out -- in fact, the tension appears to be mounting.The White House press secretary said Trump's Congress relations are 'fine'Trump and McConnell are currently not speaking following a heated phone callBoth the Legislative and Executive Branch have ambitious goals for this fall 
 Question:Earlier in the morning, the President had also criticized _'s handling of raising the debt ceiling.

Input: Consider Input: (CNN) Sometimes a historic moment arrives like an IMAX movie: a big, loud, jarring event that bends the arc of history. Other times, though, it sneaks up on people. It seems modest at the time, but only later do Americans realize it marked a turning point -- that something new had burst onto the national stage and the old rules no longer applied. Did President Barack Obama have such a moment this week when he wept openly about children killed by gun violence? Some say yes, and that Obama's tears were more radical than people realize. Most people know the backdrop: While announcing executive orders Tuesday to strengthen gun control laws, Obama halted as the cameras clicked. He tried to regain his composure, but then the tears flowed as he talked about 20 schoolchildren murdered by a gunman at Sandy Hook Elementary School in 2012.Obama's tears during his gun control speech were revolutionary, several historians and political scientists sayHe became the "father-in-chief," shedding tears over the deaths of white children, they sayHe also showed it was OK for men -- and political leaders -- to cry in public 
 Question:"He's us, and in many ways, that's _'s greatest triumph."


Output: Barack Obama
