Transcript for President Trump directed ex-fixer Michael Cohen to lie to Congress, report says
We're gonna begin here with Michael Cohen the president's former fixer and attorney Democrats in the House of Representatives are vying to get to the bottom. Of a new report lot of buzz feed that suggests president trump directed are instructed Michael Cohen. To lie when he testified before congress about a project to build. A trump branded skyscraper. In Moscow for more on this we're joined by our Chief Justice correspondent Pierre Thomas in Washington. Here we have not been able to independently. Verify this report here at ABC news but. If true it's potentially significant. Well if it is true and if Mueller of the special counsel team can corroborate this information it would be significant because it would suggest. That the president would have been involved in potentially obstructing justice and again. ABC news is not confirmed and cannot corroborate the story we're doing our own reporting on the story. Trying to check this out. But again if true.

Democrats trying to maybe box to new attorney general nominee into a corner here. Potentially but again. At the end of the day this case is going to be built or not on whatever evidence Bob Mueller. Can find to lay out what did or did not happen. And it again the point of businesses here is that whenever Michael Cohen may have sex is special counsel. There's gonna have to be a lot of evidence to go to support. ABC's Pierre Thomas our Chief Justice correspondent with us from Washington Peter thanks a.
