Question: The halftime score Saturday was 27-0  after Notre Dame quarterbacks  Brandon Wimbush  and Ian Book combined to complete 5 of 16 passes for 63 yards. And they threw three picks.
The first came after  Brandon Wimbush  threw too high for Equanimeous St. Brown  and the deflection floated into the hands of safety Jaquan Johnson. Miami staffer Joel Rodriguez draped the gaudy 5 1/2-pound chain around the neck of Johnson.
The second pick came after  Wimbush  threw a mile high of Chase Claypool. Miami's Malek Young took full advantage  snatching the ball.
Down 20-0  Notre Dame coach Brian Kelly benched  Wimbush  in favor of Book. That move was futile.
Here  you take it: Notre Dame had been one of the nation's stingiest teams in terms of turnovers heading into its clash with Miami. The Irish had coughed it up just seven times â four interceptions and three lost fumbles â in nine games. But Miami's turnover chain choked them Saturday.  Brandon Wimbush  threw two picks and surrendered the ball on a fourth-quarter hit. Backup Ian Book added a pick-six to  his  permanent record.

Answer: Brandon Wimbush


Question: Russian President Vladimir Putin has a "bad" untold secret about Donald Trump that will eventually come out  Joe Scarborough said on Friday.
" Vladimir Putin  has something on Donald Trump " Scarborough charged Friday on  his  "Morning Joe" show on MSNBC.
"Let me say it again  because thereâs been a lot of noise from Donald Trump over the past year since heâs been president.  Vladimir Putin  has something that  he  is holding over Donald Trumpâs head. And it is bad."
"So what is Donald Trump hoping? He is not hoping he can just brush aside a story of a porn star. Heâs hoping when the truth comes out about what  Vladimir Putin  has and has had hanging over  his  head for decades  possibly  that we will all be too numb to notice " Scarborough said.
"Ten tweets a day  five lies a day  bread and circuses  all of these game show  reality show distractions ... Thatâs all  he âs hoping.  He  wants to numb the American people.  He  wants to numb the electorate.  He  wants to numb everybody."
Scarborough did not elaborate on what information  Putin  may have about Trump.
The commander in chief has been criticized for what one Democrat called his "bromance" with  Putin . And in November  Sen. John McCain slammed Trumpâs comments that he sincerely believed  Putin  meant it when  he  said  he  didnât meddle in the 2016 presidential election.

Answer:
Putin
