On September 5, 2007, during a visit to Concord, New Hampshire, Tancredo made it clear that he supports strictly enforcing immigration laws and deporting all illegal immigrants. He believes so-called sanctuary policies provide safe havens for criminals. Tancredo also mentioned his support of the building of a fence between Mexico and the United States, and that mayors and city council members who adopt sanctuary city policies should face criminal charges. He urged New Hampshire Governor John Lynch to veto an upcoming immigration bill and demanded the ouster of the bill's sponsors.
