The man appeared at locations where the elder daughter of the 44th president was interning on April 10, 11 and 12, the sources said. 
  
 Authorities are investigating an alleged stalker who showed up at Malia Obama's workplace in Manhattan on three separate days earlier this month with a sign proposing marriage, law enforcement sources said. 
  
 Jair Nilton Cardoso appeared at locations where the elder daughter of the 44th president was interning on April 10, 11 and 12, the sources said. In the first instance he even slipped past security at a building in Tribeca, got to the fourth floor and begged Malia to marry him, according to the sources. 
  
 He reportedly wanted to marry Malia so he could get to former President Barack Obama and ask for some kind of help for his country, sources said. He hasn't made any verbal threats to her, according to sources, but the frequent run-ins have raised concerns. 
  
 The Secret Service detained Cardoso and took him to the NYPD's First Precinct, which in turn referred him to Kings County Hospital for evaluation, according to the sources. No charges were pending against him Wednesday evening, sources said. 
  
 Malia Obama still qualifies for Secret Service protection under a recently signed executive order. 
  
 Former NYPD sergeant and FBI special agent Manny Gomez said there is reasonable fear for Malia's safety and that is the classification of stalking under New York State law. 
  
 "I'm sure an order of protection will be served in the not so distance future," Gomez said. 
  
 It was not immediately clear where Cardoso was as of late afternoon Wednesday. The NYPD referred inquiries to the Secret Service, who said "we don't discuss our protective operations." 
  
 The Manhattan district attorney's office declined comment. 
  
 There were media reports that Cardoso was known to the Secret Service from previous appearances at the White House during the Obama administration, though he has no record of arrests, according to court information, in Washington, D.C. ||||| The agents recognized Cardoso as a man who had repeatedly tried to get into the White House in the past, sources said. They told him to leave the Tribeca building and to leave her alone, sources said. ||||| Malia Obama leaves the State Dining room of the White House , January 12, 2017.

 NEW YORK (CBSNewYork) — An emotionally disturbed Brooklyn man has undergone a psychiatric evaluation for allegedly stalking and harassing Malia Obama. 
  
 On April 18, Secret Service agents went to the NYPD precinct in Tribeca to report multiple harassing incidents involving the eldest daughter of former President Barack Obama. 
  
 According to the Secret Service, on April 10, Jair Nilton Cardosa, 30, went to the fourth floor of the Tribeca office where Obama was working as an intern, put a sign on a window and repeatedly yelled to her asking her to marry him. 
  
 The two Secret Service agents assigned to Obama’s detail told him to leave. 
  
 On April 12, Cardosa followed Obama out of a different office in Tribeca where she is also working as an intern and was stopped by two Secret Service Agents. Those agents identified Cardosa as the same man who tried to enter the White House on several previous occasions. 
  
 Again, he was sent away without law enforcement action. 
  
 On April 13, Secret Service agents went to Cardosa’s apartment on Flatbush Avenue to interview him. 
  
 They determined him to be emotionally disturbed and was taken to Kings County hospital for a psych evaluation. 
  
 None of the previous alleged stalking incidents were reported to the NYPD until Tuesday. 
  
 Cardosa has not been charged but harassment and stalking charges are being considered by the NYPD. |||||

A 30-year-old man is facing possible charges for allegedly stalking and harassing Malia Obama, the New York Daily News reports. According to NBC New York, Jair Cardoso showed up at the New York City building where the 18-year-old daughter of the former president is interning three days in a row, from April 10 to April 12. Sources say on April 10 Cardoso held up a sign and yelled for Obama to marry him before Secret Service agents told him to leave. Two days later, he was stopped by agents while allegedly following Obama after she left her internship, CBS New York reports. On April 13, Secret Service agents interviewed Cardoso at his apartment and took him to the hospital for a psychiatric evaluation. Sources say Cardoso is trying to use Obama to get to her father, who he wants to ask for help. Agents believe Cardoso, who they say repeatedly tried to get into the White House in the past, is emotionally disturbed. The Secret Service filed police reports regarding Cardoso's alleged behavior on Tuesday. The NYPD is considering stalking or harassment charges, though none have yet been filed.
