Senate President Franklin Drilon said yesterday that US Ambassador Francis Ricciardone had apologized for the incident over the telephone.
Ricciardone gave assurance that he would ask for a "full report from Washington" regarding the incident, Drilon said.
"They (US immigration) need a lecture on how to deal with people who go to the US. They have a job to do but I am sure they can do it with more decorum and respect," he added.
A ranking official of the Department of Foreign Affairs, who requested anonymity, said the Philippines may file a diplomatic protest against the US because the former first lady had not violated US immigration laws.
"We have reasons to complain," the official said. "If these are the facts presented, we have grounds to file a protest. She (Ejercito) is a senator and should be given courtesy."
Quoting Ejercito, Drilon said the senator and her party were met at the arrival area by agents of the US Department of Homeland Security and were immediately segregated from the other passengers.
Drilon, himself a "victim" of US immigration’s strict security measures in 2002, said Ejercito was held in a cubicle at the airport, where US immigration officials led by a Filipino-American identified as "Pangan" interrogated her for an hour and a half about her husband’s case.
"Such questions had nothing to do with US immigration laws," he said in a statement.
"I wonder why a member of the Philippine Senate had to be subjected to such irrelevant questioning. They need some lecturing on how to deal with people who go to the US. They have a job to do, but I am sure that they can do it with more decorum and respect," he said.
Drilon did not say whether Ejercito’s daughter, Jacqueline Ejercito-Lopez, and her grandchildren, who were traveling with her, were also detained and interrogated.
Drilon said Ejercito called him up yesterday to complain that she had been "harassed" by US immigration officials upon her arrival in San Francisco.
"As Senate president, I denounce this shabby treatment of a duly elected Filipino senator at the hands of US immigration officials," he said.
"These unnecessary and uncalled for cases of harassment of Filipino officials at US airports should stop," he said.
Ejercito had asked permission from Drilon to travel to the US to speak before the Filipino community in San Francisco and Los Angeles. She will be back on April 9.
Last year, Sen. Juan Ponce Enrile said the US Embassy canceled his multiple-entry visa because of security concerns that had not been explained to him.
In 2002, US immigration officials stopped Drilon also at San Francisco International Airport and asked him to remove his shoes as part of strict security measures. — With Pia Lee-Brago
