Washington - The National Republican Convention today enters its second day, amid protests and tensions instigated by delegates opposed to the nomination of possible Republican presidential candidate, Donald Trump.

The anti-Trump Republican delegates staged angry protests yesterday in the convention´s plenary session at the Quicken Loans Arena in Cleveland, Ohio, after failing in their bid to challenge the nomination of the real estate magnate.

Republican party leaders yesterday blocked a motion presented by the group opposed to the candidacy of Trump, who had tried to force a vote against the billionaire.

The protesters demanded a second nominal voting, but the president of the convention rejected the claim saying there were enough signatures to make the first vote count. In turn, the Trump campaign lashed out at the Governor of Ohio and former presidential candidate, John Kasich, for refusing to support the New York billionaire.

The head of the campaign committee of the New York aspirant, Paul Manafort, described as "stupid" Kasich´s decision to not support the possible Republican candidate. This elicited a response from John Weaver, one of the advisers to the Ohio governor, who described Manaford as being a representative of "thugs and autocrats."

The Republican National Convention will discuss very hot issues such as racial violence, police abuse, immigrants and terrorism, in the coming three days of the event.
