Rep. Steve Stockman (R-TX) on Wednesday praised Sen. Ted Cruz’s (R-TX) marathon speech against Obamacare on the senate floor via Twitter, contrasting the senator’s stamina with President Barack Obama’s response to the attack on the American consulate in Benghazi, Libya.

“Ted Cruz stayed up all night to fight ObamaCare,” Stockman wrote. “Obama went to bed while Ambassador Stevens was being murdered.”

The Obama administration’s handling of the Benghazi attack, in which four people including Ambassador Chris Stevens were killed, remains a heated issue among Republicans. Some members of Congress used the first anniversary of the Benghazi attack on Sept. 11 to suggest that the White House had failed to answer their questions and could be hiding evidence from the attack.
