CONCORD, N.H. — Former Secretary of State Alexander M. Haig Jr., who received less than 1% of the vote in the Iowa precinct caucuses and is running last in polls in New Hampshire, has called a news conference today to discuss the future of his presidential campaign.

Asked if Haig would announce he was dropping out of the race for the Republican nomination, Brian Sweeney, his campaign manager, said: “I can’t comment on that.”

Sweeney would only say that Haig intended “to discuss the future of our campaign.”
