No wonder he didn't check it!
From the NY Times a tale of mice and men:
Venezuelan businessman, Guido Antonini Wilson, 46, was stopped with a suitcase stuffed with cash by an airport customs official after arriving in Buenos Aires from Caracas on a plane chartered by the Argentine government’s national energy company.
The plane also carried four executives from Venezuela’s state oil company, Petróleos de Venezuela, and three Argentine government officials. The money’s source, and for whom or what it was intended, is still under investigation. But within days, (President) Kirchner dismissed Claudio Uberti, the Argentine official who had offered Mr. Antonini Wilson a seat on the plane. He also demanded answers from the government of President Hugo Chávez of Venezuela. “I am not covering up anything,” Mr. Kirchner said at a public event last week, according to news reports. “My hands are clean."
In a news conference late last week, María Luz Rivas Diez, the Argentine attorney general, said Mr. Antonini Wilson had made 12 trips to Argentina in the past year, some for less than a day.
She told a Buenos Aires radio station over the weekend that she could not rule out money-laundering as a possible motivation, nor filing charges against Mr. Antonini Wilson, who had been allowed to leave Argentina and whose whereabouts were unknown.
Secondly, this incident may prove to be a roadblock in the ever closer Venezuela-Argentina relationship. Chavez has recently re-financed a chunk of Argentine debt and signed agreements to provide natural gas to Argentina. The mighty have clearly fallen but Argentines can't be happy with this new dependence on Venezuela, and according to todays WSJ (editorial page so take it for what its worth) "The suspicion is that the cash was intended to play a role in October's presidential election" . Kirchner has, via his chief of staff, called on Chavez (who referred to the incident as a "US plot") to apologize. In response Roberto Hernández, vice president of Venezuela’s lower house, said President Chávez “doesn’t have to say sorry” to anyone.
