Texas Gov. Rick Perry vowed Saturday to fight the indictment against him, calling it an "outrageous" abuse of power.

"This indictment amounts to nothing more than abuse of power and I cannot and will not allow that to happen," Perry said at a news conference a day after he was charged with violating state law.

On Friday, a Travis County grand jury indicted Perry on two felony counts for allegedly abusing the powers of his office by carrying out a threat to veto funding for state prosecutors investigating public corruption -- making the possible 2016 presidential hopeful his state's first indicted governor in nearly a century.

A special prosecutor spent months calling witnesses and presenting evidence that Perry broke the law when he promised publicly to nix $7.5 million over two years for the public integrity unit run by the office of Travis County District Attorney Rosemary Lehmberg. Lehmberg, a Democrat, was convicted of drunken driving, but refused Perry's calls to resign.

Though the Republican governor now faces two felony indictments, politics dominates the case.

Lehmberg is based in Austin, which is heavily Democratic, in contrast to most of the rest of fiercely conservative Texas. The grand jury was comprised of Austin-area residents.

The unit Lehmberg oversees investigates statewide allegations of corruption and political wrongdoing. It led the investigation against former U.S. House Majority Leader Tom DeLay, a Texas Republican who in 2010 was convicted of money laundering and conspiracy to commit money laundering for taking part in a scheme to influence elections in his home state -- convictions later vacated by an appeals court.

Mary Anne Wiley, Perry's general counsel, predicted Perry ultimately will be cleared of the charges against him -- abuse of official capacity and coercion of a public servant.

"The veto in question was made in accordance with the veto authority afforded to every governor under the Texas Constitution," she said.

David L. Botsford, Perry's defense attorney, whose $450-per hour fees are being paid for by state funds, said he was outraged by the action.

"This clearly represents political abuse of the court system and there is no legal basis in this decision," Botsford said in a statement. "Today's action, which violates the separation of powers outlined in the Texas Constitution, is nothing more than an effort to weaken the constitutional authority granted to the office of Texas governor, and sets a dangerous precedent by allowing a grand jury to punish the exercise of a lawful and constitutional authority afforded to the Texas governor."

Several top aides to Perry appeared before grand jurors, including his deputy chief of staff, legislative director and general counsel. Perry himself did not testify, though.

Abuse of official capacity is a first-degree felony with potential punishments of five to 99 years in prison. Coercion of a public servant is a third-degree felony that carries a punishment of two to 10 years.

In office since 2000 and already the longest-serving governor in Texas history, Perry isn't seeking re-election in November.

When he ran for president in 2012, Perry plummeted from brief front-runner to national punchline, his once promising campaign doomed by a series of embarrassing gaffes, including his infamous "Oops moment" during a debate.

As he eyes another White House run, Perry has re-made his cowboy image, donning stylish glasses, studying up on foreign and domestic affairs and promising conservatives nationally that he's far more humble this time around.

Political observers say the indictment may not immediately hurt his standing with Republican primary voters -- but Democrats didn't miss a change to gloat Friday.

"Texans deserve real leadership and this is unbecoming of our governor," Texas Democratic Party Chairman Gilberto Hinojosa said in a statement. He demanded that Perry immediately resign.

No one disputes that Perry is allowed to veto measures approved by the Legislature. But the left-leaning Texans for Public Justice government watchdog group filed an ethics complaint accusing the governor of coercion because he threatened to use his veto before actually doing so in an attempt to pressure Lehmberg to quit.

"We're pleased that the grand jury determined that the governor's bullying crossed the line into illegal behavior," said Craig McDonald, executive director of Texans for Public Justice. "The complaint had merit, serious laws were potentially broken."

Michael McCrum, the San Antonio-based special prosecutor, said he "took into account the fact that we're talking about a governor of a state -- and a governor of the state of Texas, which we all love."

"Obviously that carries a lot of importance," McCrum said. "But when it gets down to it, the law is the law."

McCrum said he'll meet with Botsford on Monday to discuss when he will come to the courthouse to be arraigned. McCrum said he doesn't know when Perry will be booked.

Perry and other high-profile Republicans said Lehmberg should resign after she was arrested and pleaded guilty to drunken driving in April 2013. A video recording made at the jail showed Lehmberg shouting at staffers to call the sheriff, kicking the door of her cell and sticking her tongue out. Her blood-alcohol level was nearly three times the legal limit for driving.

The indictment of Perry is the first of its kind since 1917, when James "Pa" Ferguson was indicted on charges stemming from his veto of state funding to the University of Texas in an effort to unseat faculty and staff members he objected to. Ferguson was eventually impeached, then resigned before being convicted.

Gromer Jeffers, political writer for The Dallas Morning News, said the indictment was surprising.

"We knew a grand jury was looking at this, but you never expect a sitting governor to be indicted," Jeffers said. "It's a felony indictment, so it's pretty serious. These are charges he'll have to fight and fight vigorously. It could result in some serious punishment. They're serious charges."

Jeffers said he has no doubt the indictment will hurt Perry's potential run for president in 2016.

He said recently the governor had been making good traction by taking a stand in the Border Crisis and visiting key election states such as Iowa.

"He was headed in the right direction. This will hurt. If you remember when allegations were made about Chris Christie and abuse of power, he plummeted in the polls. And those were just allegations and not an indictment."
