A few political tweeters shared their sympathies on Friday with those affected by Thursday's plane crash in Central Cuba and by the Fort Hood shooting one year ago.

"My condolences go out to those who lost loved ones in the plane crash in #Cuba," tweeted Assistant Secretary of State Arturo Valenzuela. He also sent a version of the message in Spanish. 

The New York Times reports that all 68 aboard the plane were killed.

Meanwhile the Fort Hood shooting anniversary was noted by Sen. John Cornyn (R-Texas).

"On today’s one year anniversary of the shooting at Fort Hood, my thoughts are with the families who lost loved...," he said, linking to a statement.

It read, in part:

"Today we pause to honor the 13 killed, the many wounded and countless others affected by the senseless, violent attack at Fort Hood one year ago. My thoughts and prayers are with the families and loved ones who are still struggling to cope with this tragedy and loss, as well as the greater Fort Hood community as they honor those lost and the heroes who put themselves in harm’s way on that fateful day.

“As the largest military installation in the free world, Fort Hood has long been a source of pride for Texans and all Americans. I am pleased to see today that this fine post and the community that supports it have rallied together and emerged even stronger following last year’s tragedy." 

The gunman, identified as Army Maj. Nidal Hasan, faces charges of 13 counts of premeditated murder and 32 counts of attempted premeditated murder. An ongoing Article 32 procedure will determine whether he should face a court-martial.

Rep. Kay Granger (R-Texas), in a later series of tweets, plugged the Fort Hood Families Benefits Protection Act which treats victims and their families as if they had been in combat action.

"We will never be able to replace the loss they have experienced, but hope they know they still have an entire nation’s support behind them," she tweeted

Adm. Mike Mullen also remarked on the anniversary on his feed.

"My thoughts and prayers today for the wounded and families of those lost at Ft Hood; thx to the heroes who took action, saved lives," he said.

Note: Earlier in the week, two lawmakers from Michigan also noted the passing of famed MLB manager George "Sparky" Anderson, best known for his back-to-back World Series titles in 1975 and 1976 as manager of the Cincinnati Reds. 

"Our thoughts and prayers go out to the family of former Tigers' manager Sparky Anderson," tweeted Rep. Thaddeus McCotter (R-Mich.) on Thursday morning.

Sen. Debbie Stabenow (D-Mich.) also tweeted the link to a statement on Anderson.
