The White House has officially refused to co-operate with the impeachment inquiry against presIdent Donald Trump.
According to media reports, a letter sent to democratic leaders rejected the inquiry as baseless and constitutionally invalid.
Three democratic-led house committees are investigating president trump.
The inquiry is trying to find out if president held back aid to Ukraine to push it to investigate Joe Biden who is running for the democratic presidential nomination.
The White House letter comes hours after the trump administration blocked the us ambassador to European Union from appearing before a congressional impeachment investigation.
Meanwhile, top US democrat and house speaker Nancy Pelosi in response to white house refusal to cooperate in impeachment probe termed it an “unlawful attempt to hide the facts”.
The house speaker in a statement responded by saying the letter is manifestly wrong, and is simply another unlawful attempt to hide the facts of the trump administration’s brazen efforts to pressure foreign powers to intervene in the 2020 elections.
