While many see the tweets, particularly the one suggesting mass voter fraud, as problematic, House Speaker Paul Ryan is not among them.

Since his election as the next president, Donald Trump has continued to use Twitter as one of his favored means of communication.
While many see the tweets, particularly the one suggesting mass voter fraud, as problematic, House Speaker Paul Ryan is not among them. 
During an interview with CBS' ‘60 Minutes’ broadcast on Sunday, Ryan was pressed for comment on Trump’s assertion that millions of illegal votes were cast in the recent election. 
Ryan responded, in part, “I have no way of backing that up. I have no knowledge of such things…it doesn’t matter to me. He won the election. The way I see the tweets you’re talking about, he’s basically giving voice to a lot of people who have felt that they were voiceless…He’s going to be an unconventional president.”
He continued, “Who cares what he tweeted, you know, on some Thursday night, if we fix this country’s big problems? That’s just the way I look at this.” 
Trump’s pick for White House chief of staff, Reince Priebus, also weighed in on the controversial tweet during a CBS interview on Sunday.
On ‘Face the Nation,’ Priebus said of Trump’s voting-related allegation, “Well I don’t know if that’s not true...I saw that there was an article in the Wall Street Journal the other day and it had a certain percentage of people that are voting that shouldn’t be voting. There are estimates all over the map on that. And here’s the problem--no one really knows.”
