PHOENIX — The Arizona House of Representatives on Monday failed to reach a budget deal after hours of tenuous discussions and a called off vote that left a frustrated Speaker Andy Tobin huddled with members of his own party who refused to back a plan he endorsed.

Tobin had scheduled debate and votes Monday afternoon on the $9.2 billion spending plan for the coming budget year approved by the Senate last week. But as the day dragged on it became clear he was having trouble getting enough votes. House members spent hours waiting for him to call them into session.
