[1][2] In July 2009, following the resignation of scandal-plagued minister Monica Iacob Ridzi, Plăcintă was given the Youth and Sport portfolio and sworn in the same day.
[3] Her appointment was criticised by Vrancea County Council and PSD chapter president Marian Oprișan, who noted her links to the ministry were as close as those between "an old woman and a machine gun",[4] and who pointed out she had contributed hundreds of thousands of euros to her party.
[6] In October 2009, she became interim Minister for Relations with Parliament following the resignation of her PSD cabinet colleagues, including Victor Ponta, the previous occupant of that ministry, holding the portfolio until December.
