of documents from donald trump. and the committee asked his daughter ivanka for cooperation. nbc s julie tsirkin is on capitol hill for us. julie, welcome on this sunday. what are you hearing about ivanka today? reporter: chairman bennie thompson spoke about her this morning and reminded us how expansive their investigation has been. remember, they started with a public hearing last december when they heard emotional testimony from the officers on january 6th. next they moved into that investigation phase that they re still in now. you mentioned those 700 pages of documents. well, they faced obstruction after obstruction from former president trump and his allies, calling the investigation delegitimate, trying to delegitimize the investigation and paint it as solely partisan. those 700 pages, of course, we know some of those at least was that unsigned executive order reported on by politico that instructed our military to go and seize voting machines around the country.
