Washington D.C. - Republicans in the House of Representatives hope to offer President-elect Donald Trump an alternate plan to his proposed U.S.-Mexico border wall, a first test by lawmakers from his own party of one of his key campaign promises.

Just a day after Trump's stunning election victory over Democrat Hillary Clinton, congressional aides told Reuters the lawmakers wanted to meet with Trump's advisers to discuss a less costly option to his "big, beautiful, powerful wall."

The plan would involve more border fencing and additional border staffing with federal agents, many of whom belong to labor unions that supported Trump's candidacy, the aides said. The House aide said House Republicans working on the alternative plan were waiting for Trump's transition team to be put in place before setting a date for the meeting.

A spokesman for Trump did not respond to a request for comment on the lawmakers' proposal or their desired meeting.
