Liar liar pants on fire.
"The House did ask Bolton to testify . But Bolton, who left his post in September, declined to do so at the White House’s directive. The White House successfully blocked a number of officials from testifying or producing documents relevant to the House’s investigation.
Bolton signaled that he would testify only if he were subpoenaed and if a court ruled that he should obey the subpoena over the White House’s instructions."
Why didn’t they subpoena him, they had that authority.
