Schiff, who assumed the committee chairmanship after Democrats won control of the House of Representatives in November elections, outlined lines of inquiry it intends to pursue on Russian election activities, possible Trump campaign ties and matters relating to Trump's business dealings.
A day after the Republican president warned Democrats against "ridiculous partisan investigations" in his annual State of the Union address, Schiff said they would not be intimidated.
Democrats complained forcefully a year ago that Republicans had blocked their effort and denied their request to subpoena key witnesses. California Congressman Adam Schiff said in a statement that the interview has been rescheduled for February 28 "in the interests of the investigation".
As part of that oversight, Schiff said the committee would be broadening the parameters of its investigation into interference by Russian Federation and other foreign entities during and since the 2016 election.
"The special counsel's office, the Justice Department and its elements will now have access to those transcripts for any objective which will facilitate justice", Schiff told reporters after the committee's vote, adding that the transcripts will be sent to Mueller's investigators immediately.

House Intelligence Committee Chairman Adam Schiff on Wednesday revealed a sweeping plan to investigate President Donald Trump, including whether foreign actors have leverage over the Republican, his family or associates. He also noted, "That pertains to any credible allegations of leverage by the Russians or the Saudis or anyone else".
To protect ongoing investigative interests and information that remains classified, the Committee will release transcripts in a manner and according to a timetable that allows continued pursuit of important leads and testimony, while ensuring that the American people have faith in the process and can assess for themselves the evidence that has been uncovered, while legitimate national security interests continue to be protected. Both have pleaded guilty or been indicted for lying to Congress.
They criticized the Office of the Director of National Intelligence declassification review of documents already approved for release in the last Congress as "unacceptable", and added that "we hope the Democrats will now join us in further increasing transparency by voting to immediately publish all the unclassified transcripts that we previously sent to the executive branch". ODNI has said the transcripts may be ready by May or June of this year.
The committee also announced Wednesday the reorganization of its subcommittee structure.
