Intelligence officials have declined to brief electors on the extent of Russian interference with the election before they cast their ballots for president Monday, NPR has reported.

A group of 54 Democratic electors wrote an open letter to Director of National Intelligence James Clapper last week asking him to explain how Russian cyberspies hacked Democratic e-mail accounts and whether they did so to help elect Donald Trump, but NPR says Clapper refused the request late Friday.

Election-night tallies showed Trump with 306 electoral votes to Hillary Clinton’s 232. The count is likely to stay the same in Monday’s Electoral College vote, as electors are bound to cast ballots based on the results in their state.

Many Republican members have reported receiving hateful mail, e-mail and calls urging them to reject Trump.
