Leaders of the House Intelligence Committee's probe into Russia's efforts to meddle in the 2016 elections said Tuesday that their "aggressive" investigation is ongoing.

Rep. Mike Conaway, R-Texas, and Intelligence Committee Ranking Member Adam Schiff, D-Calif., gave few details at a press conference they called — and took no questions from the press. Schiff said he and Conaway plan to invite former Obama Department of Homeland Security Secretary Jeh Johnson to testify before their committee, both in a closed and open session, where he could hopefully provide more insight into the intelligence community's conclusion on Oct. 7, 2016, that they were "confident that the Russian government directed the recent compromises of emails from U.S. persons and institutions, including from U.S. political organizations."

The two said the committee plans additional open hearings soon. Their investigation is just one of at least three ongoing into Russian meddling and potential ties between the Trump associates and Russia. The Senate Intelligence Committee is holding its own concurrent investigation, where former FBI Director James Comey, fired last month by President Trump, is set to testify in a highly anticipated session on Thursday.

Former FBI Director Robert Muller was also appointed last month as a special counsel to oversee the Justice Department's growing probe.

Conaway took over the GOP side's lead on the House investigation when Committee Chairman Devin Nunes, R-Calif., stepped aside after the House Ethics Committee opened an inquiry into whether he improperly disclosed classified information.
