WASHINGTON (Reuters) - U.S. presidential hopeful Donald Trump is expected on Thursday to pledge that he will not run as an independent candidate if he loses the Republican Party's nomination, ABC News reported, citing a source familiar with Trump's conversations with the party.
Trump, a real estate mogul, has suggested he would consider an independent run if Republicans did not nominate him as their candidate. The Republican National Committee has asked its pool of 17 candidates to sign a loyalty pledge to ensure future party unity.
ABC News reported that Trump has not told Republican leaders directly how he planned to handle the pledge, but a Trump spokeswoman said he would make a decision Thursday.
One of Trump's key rivals, Jeb Bush, the former Florida governor, told ABC's "Good Morning America" on Thursday he would back Trump if the businessman-turned-politician won the party's nomination for the 2016 presidential election and Hillary Clinton is the Democratic nominee.
Trump, on the same program, also said he would back Bush over Clinton.
Reuters/Ipsos polling shows Trump with support among nearly 31 percent of self-identified Republicans as of Sept. 1 with Bush garnering support among nearly 12 percent, behind former neurosurgeon Ben Carson.
