(CNN) - As Vice President Joe Biden leaves open the door to another presidential run, his trip next week to New Hampshire will likely fuel more speculation about his interest in the job.
Secretary of Labor Thomas Perez will join him to highlight NH Works, an on-the-job training program that works with 170 businesses statewide. As he announced in his State of the Union address earlier this year, Obama tasked Biden to lead job-training reform.
"Vice President is working with organizations, federal agencies, and others to make the workforce and training system more job-driven, integrated, and effective. The Vice President’s visit to New Hampshire is part of his ongoing efforts to find the best ways to improve the system," a White House official said.
As the state that holds the first-in-the-nation presidential primary, New Hampshire is known as a prime stomping ground for potential White House candidates.
Biden said last month that he has "absolutely" not ruled out another White House run.
"It’s as likely that I run as I don’t run. I just truly haven’t made up my mind," he said on "The View."
Polls measuring support for 2016 consistently indicate Biden falls behind former Secretary of State Hillary Clinton at a distant second place. In a CNN/ORC International Poll released earlier this month, for example, Clinton came in with 64% compared to 13% for Biden among Democrats.
Clinton says she still hasn't decided on whether she'll pursue another campaign, but Biden said her decision won't be a factor in his own consideration.
"Whether she runs or not will not affect my decision," he said.
Earlier in February, Biden told CNN's Kate Bolduan he plans to decide in the summer of 2015, and "there's no obvious reason for me why I think I should not run."
Still, the vice president and former six-term senator has said 2016 is "lifetimes away."
Biden last traveled to an early voting state in September, when he went to South Carolina for an official visit on jobs and infrastructure.
The day before, however, Biden delivered the keynote speech at Democratic Sen. Tom Harkin's annual steak fry in Iowa, an event that typically attracts a high-profile crowd of national Democrats and tends to draw potential White House hopefuls.
In August, Biden was scheduled to travel to Maine for a fundraiser for New Hampshire Gov. Maggie Hassan, but he had to cancel the trip because his son, Delaware Attorney General Beau Biden, became seriously ill.
When Biden ran for president in 2008, he did not compete in the New Hampshire primary, having dropped out after a poor showing in the Iowa caucuses.
