WASHINGTON - The Bush administration is poised to suspend a major post-9/11 security initiative to cope with increasingly angry complaints from Americans whose summer vacations are threatened by new passport rules.

A proposal set to be announced as early as Friday will temporarily waive a requirement that U.S. passports be used for air travel to and from Canada and Mexico, provided the traveler can prove he or she has already applied for a passport, officials said Thursday.

The suspension in the rules is aimed at clearing a massive backlog of passport applications at the State Department that has slowed processing to a crawl, they said. Some officials said the change would last several months; others said as long as six months.
