A strict constructionist, Tyler found much of the Whig platform unconstitutional, and he vetoed several bills favored by party leader Henry Clay. Among the bills vetoed by Tyler was a measure to re-establish a national bank. In response to these vetoes, most of Tyler's cabinet resigned, and Whig congressmen expelled Tyler from the party. A resolution calling for his impeachment was introduced in the House, though it was later defeated. Despite his disagreements with Congress, Tyler did sign the Tariff of 1842, which provided needed revenue to a government still dealing with the effects of the Panic of 1837. On March 1, 1845, three days before turning the presidency over to Polk, Tyler signed a Texas annexation bill into law, and Texas would be admitted as a state in the first year of Polk's presidency.
