Former national security adviser John Bolton wont appear to answer questions from Congress in the impeachment inquiry against President Donald Trump unless hes subpoenaed, his lawyer said.
Boltons attorney Chuck Cooper said late Oct. 30 that Bolton will not appear without a subpoena.
Democrats have issued subpoenas to several other witnesses who ended up testifying.
Lawmakers want to hear from Bolton after other witnesses told them of his concerns with Trumps dealings in Ukraine and the backchannel activities of Rudy Giuliani, Trumps personal lawyer.
Trump asked Ukrainian President Volodymyr Zelensky in a July phone call to look into CrowdStrike, a company hired by the Democratic National Committee to investigate a network breach, and also into former Vice President Joe Biden and Bidens son, Hunter Biden.
Biden said last year that in 2016 he threatened to withhold $1 billion in aid from Ukraine unless then-President Petro Poroshenko ousted Viktor Shokin, a prosecutor who was probing Burisma.
Hunter Biden was on the board of Burisma from 2014 to 2019.
Some Democrats have claimed Trump asked Zelensky to investigate a political rival because Biden is running for the Democratic presidential nomination to challenge Trump.
House Democrats wanted Bolton to testify on Nov. 7.
Another potential witness, former deputy national security advisor Charles Kupperman, didnt appear on his scheduled date after he filed a lawsuit asking a judge whether he should follow the argument by Trumps White House that he shouldnt cooperate due to executive privilege, or whether he should appear and testify about what he knows.
“Plaintiff is faced with irreconcilable commands by the Legislative and Executive Branches of the Government and, accordingly, seeks a declaratory judgment from this Court as to whether he is lawfully obliged to comply with a subpoena issued by the House Defendants demanding his testimony pursuant to the House of Representatives impeachment inquiry, or he is lawfully obliged to abide by the assertion of immunity from congressional process made by the President in connection with the testimony sought from Plaintiff,” the lawsuit stated.
Kupperman was an aide to Bolton while both were working for the Trump administration.
House Democrats threatened to hold Kupperman in contempt when he didnt appear to give testimony.
House Intelligence, Oversight, and Foreign Affairs committees will “obviously consider, as we inform Dr. Kuppermans counsel, his failure to appear as evidence that may warrant a contempt proceeding against him,” House Intelligence Chairman Adam Schiff (D-Calif.) told reporters.
