"This past week I have spent in reflective thought, prayer & deep sorrow," she wrote on Twitter. "I join my daughter in extending my help & services to all those affected by the diabolical act of terror which occurred in Manchester! My heart goes out to all the victims: Those who lost their lives, those injured, those recovering & all survivors of that night, along with the families & friends whose grief knows no bounds. I stand with you all in the face of evil & we stand together to never let it rule our lives! Thank you to all those who helped in any way that night in Manchester. I continually thank those who are & were in service protecting our freedoms every day all over the world! #MemorialDay"
