Real-estate mogul Donald Trump will be in Buffalo on Jan. 31 for a $500-per-couple fundraiser honoring Erie County town chairmen.

The event is being organized by Erie County Republican Chairman Nick Langworthy, who was one of several GOP officials around the state who attended a meeting with Trump in New York City this month as he mulled a possible run for governor.

Langworthy, who is supportive of Westchester County Executive Rob Astorino’s candidacy, said he came away from the meeting thinking Trump was seriously considering a gubernatorial campaign.

Even if Trump doesn’t run — he has toyed with running for president before and ultimately did not — the reality-show host’s appearance at the event is still a boost for a county chairman’s fundraiser and is sure to draw a crowd.

Trump was invited to Tuesday’s reception in Albany being thrown by the state Republican Party that is also honoring Astorino. Ultimately Trump decided not to attend given that it was an event boosting Astorino.

Trump’s potential candidacy is being backed by western New York Republicans including Assemblymen David DiPietro and Bill Nojay and political consultant Michael Caputo.
