As Vice President, Van Buren continued to be one of Jackson's primary advisors and confidants, and accompanied Jackson on his tour of the northeastern United States in 1833. Jackson's struggle with the Second Bank of the United States continued, as the president sought to remove federal funds from the Bank. Though initially apprehensive of the removal due to congressional support for the Bank, Van Buren eventually came to support Jackson's policy. He also helped undermine a fledgling alliance between Jackson and Daniel Webster, a senator from Massachusetts who could have potentially threatened Van Buren's project to create two parties separated by policy differences rather than personalities. During Jackson's second term, the president's supporters began to refer to themselves as members of the Democratic Party. Meanwhile, those opposed to Jackson, including Clay's National Republicans, followers of Calhoun, and many members of the Anti-Masonic Party, coalesced into the Whig Party.
