In a raucous conference call to reporters that included an interruption and heated exchange with one of Barack Obama's attorneys -- Hillary Clinton's campaign accused Obama supporters Tuesday of trying to hijack the Democratic presidential caucuses in Texas.

The caucuses, which require supporters to organize and pledge their votes to their candidate in an open forum, began across the state immediately after primary polls closed at 9 p.m. ET.

Shortly after their start time, Clinton campaign spokesman Howard Wolfson convened a conference call with reporters to claim that alleged irregularities in the Texas caucuses were "not typical" of the usual chaos that goes on with these events.

The Clinton team accused Obama supporters of seizing the caucus packets and signing up delegates early in the day, against the rules. They said Obama supporters took control of the caucuses and turned away Clinton caucus-goers in line at the door. They called the reports disturbing and undemocratic and said all options were on the table in regards to possibly taking the matter to court.

"We've had hundreds of complaints flooding in," said Clinton attorney Lyn Utrecht, citing comments from more than a dozen precincts in places like Houston, Dallas, Galveston and El Paso.

That's when Obama General Counsel Bob Bauer leapt into the questioning portion of the call, suggesting that the Clinton was whining because Obama has been besting Clinton in caucuses throughout the country.

He said the complaints typically arise, "only when you don't seem to get the votes you need to win," Bauer charged.

After Bauer took his leave from the call, Wolfson said to reporters, "That was Bob Bauer, someone that we all know very well, attempting a vigorous defense of the indefensible."

The campaign did not say definitively whether it would pursue a formal inquiry into the complaints.

The Texas Democratic nomination process Tuesday included a both a primary contest and subsequent caucus for the eligible 228 Texas delegates.

The process was not without other drama throughout the evening, mostly due to the high turnout, resulting in reports of long lines, shortages of paper ballots at some precincts and thousands of people crowding to get into the caucus events.

Some precincts in Houston remained open after 10 p.m. to accommodate long lines of waiting voters. Similar scenes were reported elsewhere in the state, including Travis and Tarrant counties.Texas Secretary of State Phil Wilson had projected 26 percent of the state's 12.75 million registered voters would cast ballots in the primary.

Some caucuses had to be moved outside to accommodate all of the voters while more than 2,000 people trying to attend the Democratic caucus in the North Texas town of Little Elm waited in the parking lot for about two hours before being allowed into a building to convene its meeting.
