LIZ CHENEY: TIME FOR 'NEW GENERATION' IN US SENATE: CHEYENNE, Wyo. (AP) — Liz Cheney says "it's time for a new generation" in explaining her GOP primary challenge to Wyoming's senior U.S. senator next year.

The daughter of former Vice President Dick Cheney tells The Associated Press that long-term incumbency is part of the problem in Washington these days. She says she does not view seniority "as a plus."

Cheney is challenging popular Sen. Mike Enzi, who has served three terms in the Senate. Enzi announced Tuesday that he will run for a fourth term.

A Republican incumbent facing a serious primary challenge is almost unheard of in Wyoming.

Cheney lived in Virginia until recently. Last year, she bought a home in Jackson Hole. She was born in Madison, Wis., but says Wyoming has always been her home.

. PA. MOM GUILTY OF CHARGES SHE ABUSED TWINS, 6: WASHINGTON, Pa. (AP) — A western Pennsylvania woman has been convicted of abusing and underfeeding her 6-year-old twins, one of whom was found wandering outside wearing only a shirt and diaper on a cold morning in February 2012.

Twenty-six-year-old Roxanne Taylor of New Eagle was convicted Monday. She was returned to the Washington County Jail, where she'll remain until sentencing on Sept. 13.

Taylor took the stand to say she was a "good mother." She said her children, who each weighed 30-some pounds, weren't underfed but merely "picky" eaters. Her attorney says she was guilty only of being poor, not neglectful.

But prosecutors charged her with aggravated assault, child endangerment and other crimes after finding bruises on the children and signs they were undernourished.

POLICE: MOM LEFT 2 KIDS IN CAR TO ATTEND CONCERT: WEST PALM BEACH, Fla. (AP) — A South Florida woman is facing charges after authorities say she left two young children alone in a parking lot while she attended a Lil Wayne concert.

The Palm Beach County Sheriff's Office reports that employees at the Cruzan Amphitheatre first spotted the children — ages 3 and 5 — around 7 p.m. Sunday. An employee eventually questioned the children, who said their mother had gone to the concert.

The Palm Beach Post (http://goo.gl/DXLjc ) reports that deputies caught up with 25-year-old Brittany Nicole Harris as she left the concert. Authorities said Harris initially told deputies her cousin had brought the children but later acknowledged that she had left them in the car.

Harris was arrested and charged with two counts of child neglect. She was later released on $20,000 bail.

WONDER WON'T SING IN FLA. AFTER ZIMMERMAN VERDICT: NEW YORK (AP) — Stevie Wonder says he won't perform in Florida and other states with a "stand your ground" law.

In a video posted on YouTube, the 63-year-old singer said at a concert in Quebec City, Canada, on Sunday "that until the 'stand your ground' law is abolished in Florida, I will never perform there again."

Wonder added: "Wherever I find that law exists, I will not perform in that state or in that part of the world."

The "stand your ground" law allows people to use deadly force if they believe their life is in danger.

George Zimmerman shot 17-year-old Trayvon Martin during a February 2012 confrontation in Sanford, Fla. Zimmerman said he fired his gun in self-defense.

A six-member jury acquitted Zimmerman of second-degree murder and manslaughter charges on Saturday.

MINISTER, GRANDSON FATALLY SHOT IN S. FLORIDA HOME: MIAMI GARDENS, Fla. (AP) — A minister and her adult grandson have been found fatally shot inside a South Florida home.

Miami Gardens police responded to the home Tuesday afternoon after a neighbor noticed 70-year-old Annette Anderson had not been seen outside since Saturday. Neighbors told police it was strange for her to miss church on Sunday.

Anderson was a pastor at Jesus People Ministries, and her grandson — 20-year-old Tyrone Walker Jr. — was studying to be a computer engineer.

Anderson's brother arrived and accompanied police inside where they found the bodies. Police said the two were tied up with duct tape and shot execution-style.

PA. WOMAN GETS LIFE IN FIANCE'S STABBING DEATH: ALLENTOWN, Pa. (AP) — An eastern Pennsylvania woman sentenced to life in prison in the stabbing death of her fiance on their wedding day says she still loves him.

Thirty-two-year-old Na Cola Franklin was convicted of first-degree murder in the August death of 36-year-old Billy Brewster after an argument at their Whitehall Township apartment hours before the ceremony.

Franklin said Tuesday before she was sentenced to the mandatory life term she hadn't meant to kill Brewster.

Franklin told the victim's mother in court, "I love him. I do still love him. I love him more than myself."

Defense attorney John Waldron has vowed an appeal. He argues Brewster came home drunk from an impromptu bachelor party and attacked Franklin.
