He said Lin should go back to work at the president's official residence, since that is where she is assigned.
He also urged the members of the first family to be discreet regarding their behavior since the public is watching them with a magnifying glass.
"We think the Chao family should pay for a housekeeper on their own and should give back the money the Yushan Residence paid Lin," Tsai said.
DPP legislative caucus whip Chen Chin-jun (陳景峻) also felt the party had been hurt by the controversy. He said the party felt powerless to prevent a similar controversy.
The Presidential Office did not respond to the calls for the government to be reimbursed for Lin's salary for the past six years. Office Spokesman David Lee (李南陽) said the office did not have anything new to add to its original statement.
Meanwhile, the Presidential Office also commented on the recent scandal involving alleged embezzlement from the special allowance fund.
President Chen said yesterday that he would be happy to personally explain the Presidential Office's special allowance fund to prosecutors and investigators in a bid to help establish the truth of the matter.
"The false accusations have seriously sabotaged the administration's credibility and affected the government's operations," the statement said. "We hope the public understands and respects the necessity and complexity of the state affairs the president has to handle."
As all expense accounts have been filed in accordance with procedure, the administration hopes the media would stop misleading the public and investigators with false accusations, the statement continued.
