NotiBomba has tweeted that the US Embassy is trying to persuade Hernández to concede (not clear what their source would be).
Meanwhile, the TSE itself maintains its silence.
UPDATE: Proceso Digital covered the Nasralla press conference. They quote what he said extensively; here's our translation:
"It's the first time in history that the Tribunal Supremo Electoral hasn't provided results [by the time he was speaking, midnight], but we have our own computing center and it says that with 68.4% of the actas, that is, 4,259,107 of the 6 million that the Tribunal said could vote, the actas are there”, said Nasralla.
He added that “of those that represent 68.4% of the actas, I have 45.4%, against 40.6% the the current president has, that's a difference of 4.8%, that represents 106,000 votes difference”.
Nasralla explained that two hours ago it said that there was a difference of 30,000 votes and that in the passing of the hours that progressed to 106,000.
“In light of the fact that this tendency has not changed, I can say to you that I am the new president of Honduras. I want to thank those that defended the vote”, he said.
