question:
Brandon Judd  president of the labor union  said  Agent Rogelio Martinez  died Sunday of blunt force trauma to the head.
Federal authorities have not yet said how  Martinez  was killed.
Authorities have been searching for witnesses and potential suspects after  Martinez  was killed and a fellow agent was seriously injured. Officials with U.S. Customs and Border Protection and the Border Patrol said in a statement that the pair were âresponding to activityâ near Interstate 10 in Van Horn  Tex.  when they were harmed. The other agent called for help  and other agents provided medical care and took them to a hospital.
Following news that an agent had been killed  President Trump appeared to connect  Martinez âs death to border security and plugged his plans for a border wall on Twitter on Sunday night.
Sen. Ted Cruz (R-Tex.) said on Twitter  without any further explanation  that  Martinez  and the other agent were âattackedâ and he also linked the incident to security on the border with Mexico.

Isaac Morales  who was stabbed in a bar parking lot in El Paso  was the only agent besides  Martinez  to die in 2017. Three agents died in 2016; two of them in car accidents  one of a heart attack while on bike patrol.

question:
Actress and  former model Rebecca Griffin  chose to use the death of 17 students and school staff to further  her  stance on abortion.
âWoman puts baby up for adoption  he grows up to be a violent young man who will spend the rest of his life in prison for a mass murder. Tell me more about how abortions are wrong â  Griffin  tweeted Thursday.
After fierce backlash   Griffin  would go on to blame readers for failing to properly comprehend  her  tweet and saying that  her  point was based on research showing that mental health issues are genetic  and therefore  the unfit parents of shooter Nikolas Cruz  who gave  him  up for adoption  are to blame for it.
 She  also repeatedly tweeted a link to a research paper that claimed to offer evidence that legal abortion leads to a decrease in crime.

question:
MELBOURNE  Australia â It took  Caroline Wozniacki  43 majors and two failed attempts in finals before finally claiming  her  first Grand Slam singles title.
One of the first things  she  did as a champion was apologize to top-seeded Simona Halep following  her  7-6 (2)  3-6  6-4 win in the Australian Open final on Saturday night.
"I'm sorry  I'm just taking a second to hug Daphne "  Wozniacki  said  pausing as  she  clutched the winner's trophy in the on-court ceremony. "I dreamt of this moment so many years  to be here now it's a dream come true."
More than seven years after appearing in  her  first Grand Slam final at the 2009 U.S. Open â a straight sets loss to Serena Williams  â Wozniacki  can finally erase the "but never won a major" footnote that has long been attached to  her  resume.
"I'm never going to get the question again about being a world No. 1 without a Slam "  she  said after leaving the court.
 Wozniacki  will regain the top ranking next week for the first time in six years â beating Serena Williams' record of 5 years  29 days between stints at No. 1 on the women's tour â in another benefit of beating the top-seeded Halep.
 Wozniacki  lost two U.S. Open finals â in '09 and 2014 â and Halep lost two French Open finals before their meeting at Melbourne Park.

In Halep's case   she  was the first player who had saved match points in multiple matches to have reached the final.  She  saved triple match point and rallied in the third set to beat Laura Davis 15-13 in the third set of  her  third-round match  and also needed to save match points in  her  semifinal against Angelique Kerber.
 Wozniacki  saved match points in  her  second-round win over Jana Fett and later said  she  was relaxed because for the rest of the tournament  she  was "playing with the house money."
"I know that today is a tough day "  Wozniacki  said to Halep. "I'm sorry I had to win today but I'm sure  we 'll have many matches in the future. Incredible match  incredible fight. And again  I'm sorry."
Halep was playing with an injured left ankle  needed treatment for dizziness in the second set and had rallied from a break down in the third set to lead 4-3 when  Wozniacki  took a medical time out to have  her  left knee taped. In the end   she  just ran out of steam.
"It's not easy to talk now " Halep said at the presentation. "It's been a great tournament for  me . I started not very well with the ankle injury. I just wanted to give my best every match  which I did. Of course I'm sad I couldn't win today but Caroline was better than  me .
 Wozniacki  is the third first-time major winner in the four Grand Slam tournaments since Serena Williams won the 2017 Australian Open for  her  record 23rd Grand Slam title. Serena Williams  who beat  her  older sister  Venus  in last year's final  took time out for  her  pregnancy and the birth of  her  first child in September  and is preparing to return to competition next month.
Wozniaki was ranked No. 1 for 67 weeks  including 49 straight from Feb. 21  2011 until Victoria Azarenka replaced  her  on Jan. 30  2012.
 Wozniacki  got a break in Halep's first service game and had a chance to serve for the first set at 5-3  but the Romanian rallied to break back and to force a tiebreaker. After getting an early jump in the tiebreaker   Wozniacki  won the last three points to win a set for the first time in a Grand Slam final.
