Good question since both Lee and Sessions have supported Cruz in the past. Perhaps they’re just keeping their powder dry and not endorsing in the primary, at least not yet.
That said, one of Sessions’ top aides left him and moved to work in the Trump campaign. Sessions also said he was going to give support to the person that stood up to illegals and the trade issue. Given Trump has done both, there is speculation that Sessions will endorse Trump next week:
Sessions: Choose carefully America, 2016 is ‘THE LAST CHANCE’

Alabama Sen. Jeff Sessions, a leading voice on trade, immigration and executive powers, is urging Americans to choose their next president carefully because 2016 “is the last chance for the American people to take back control of their government.”
In a sober interview with Secrets, the Republican warned that liberal special interests, Wall Street moguls, and international media conglomerates are fast turning the United States into just another member of the European Union and that the effort is being led by a Democratic president eager to go his own way with executive orders.
“This election is different because we have pell mell erosion of law, the constitutional order, where President Obama has pushed an agenda that eviscerates the immigration legal system, and pushed this trade agreement that will commence decades of transferring American economic power to an ever-expanding international commission. It’s just not going to stop” unless voters take action, he warned.
“This is the way the European Union began,” he added.
